[DBTech] vB Optimise 2.0.1 (Lite)

vB Optimise Lite

The newly revamped vB Optimise was created for vBulletin 4, but has now been made compatible for vBulletin 3.8. In this release I have re-coded vB Optimise from the gound and focused stability over features, you'll notice Phrase Caching and vBAdvanced Integration have bit the dust, this is to maintain a sync state between this version and the vBulletin 4 release.

Professional version & feature list available @ www.DragonByte-Tech.com/forum
Priority support for Lite version is handled at the Developers Website.

What does it do?

vB Optimise is intended to optimise vBulletin software by integrating several PHP "cachers" and handling data before vBulletin. This works by encountering and handling data prior to vBulletin in order to skip the arbitary execution that would be more server intensive.

Real-Life Statistics

We've teamed up with some Big Forums to show you the impact of vB Optimise, you can view this public chart which shows both our statistics and theirs:

Features

Supported Extensions
- APC
- eAccelerator
- Memcache
- XCache
- WinCache
- Filecache
Style Cacher
Caches style data to globally reduce a query within all vBulletin forum-based pages.
Template Cacher
Caches template data to globally reduce a query within all vBulletin forum-based pages.
Datastore Cacher
Forces custom datastore items from modifications (including those from vB's blogs) to use your configured Datastore Cache method instead of being forced into the database. This reduces page queries by where affected.
vB CMS Template Caching
(Automatic) Corrects many uncached templates within vB CMS to reduce upto 20+ queries on CMS pages (number varies based on content).
Optimal Settings Check
Provides a quick interface to identify possible settings which can be changed on your forum for further optimisation.
Self-System Tester
Provides a relatively straight-forward system check to ensure your vB Optimise installation works fully.
Automatic Cache Flusher
Automatically flushes cache within the Admin CP based on specific triggers to make sure content does not remain stale on your forum.
XCache Authentification
Supports XCache Admin Authentification by allowing you specify the username/password in a configuration if needs be.

Features - Pro

Notices Cacher
Caches users dismissed notices to reduce a near-global query within all vBulletin forum-based pages.
Showgroups Cacher
Caches the showgroups query which becomes more intensive as your user-base grows.
Forum Display Query Enhancement
Enhances a stock vBulletin query within Forum Display to speed up the page.
Forum Home WOL Cache
Caches Forum Home "Who's Online" to remove an intensive query and allow larger sites to display this data without impact.
vB Cache Override (Feature not available on vBulletin 3)
Ability to override vBulletins new built-in database cacher for the CMS / Forum Sidebar Blocks to remove anything from 1 to 20+ queries based on your content.
Full Guest Caching
Ability to cache entire pages and serve them saving not only hundreds of queries but upto 90% of CPU processing towards Guests.
Statistical Resource Savings
Ability to see just exactly how many queries per day vB Optimise has saved your database. You'll be surprised at the numbers.
Forum Resource Statistic
Shows off vB Optimise resource saving statistics directly within forumhome statistics.
....and more!

Release Notes

If you've used vB Optimise before you'll be aware the previous version had phrase caching, however this caused complications with the way phrases are used within vBulletin so it has not been ported over at this time.

FAQ

Q: I have WinCache installed, but vB Optimise tells me it's not?
A: WinCache only introduced OpCode support in version 1.1, if you're using version 1.0.x you will need to upgrade.

Q: I'm using the XCache method, flushing doesn't work?
A: If you have XCache authentification, turn the admin option on within vB Optimise Settings, then edit ./vboptimise/config.php and specify your XCache username/password. Alternatively you can disable XCache authentification within php.ini:

Code:

xcache.admin.enable_auth = Off

Q: I have eAccelerator installed, but vB Optimise tells me it's not?
A: eAccelerator does not provide the caching extension by default, you will need to recompile PHP with additional flags. For more information read eAccelerator documentation located here: http://eaccelerator.net/wiki/CompileConfiguration (Specifically look at: with-eaccelerator-shared-memory)

the installation.txt file is empty :(

may be u forgot :D

will try after i know how to install .. i hope its straight forward upload files and import product :confused:

Sorry, forgot to hit save on that before zipping up. Try now :)

Also yes, no file edits.

in settings page you have

Code:

vB Optimise: Online/Offline

Use this setting to turn vB Optimise online or offline.

Yes = online or offline?

Yes = online :) I'll make that a little more clear in an update I guess.

will it work on 3.7.x

Read the FAQ please :)

interesting, will keep an eye on this one :)

*clicks install* got to see if it really increases the speed..how can i do that?

anyways thanks for the mod :)

Speed can vary depending on a number of factors, I found the best results occur when using Memcache. You could turn on vBulletin debug information to check page generation times, this is my forums normal generation time (forum home):

Quote:

Page Generation 0.08814 seconds

This is simply a test forum, no mods but vB Optimise, my server also has XCache installed, when I turn vB Optimise on:

Quote:

Page Generation 0.02804 seconds

Not to mention the reduction in two queries and a chunk off another :)

you joined two days back and brought a really nice thing pretty fast. Will test it out.

Can you please explain, which 2 global queries does it reduce and which one it chunks off.

thanks

This looks interesting and promising if it does what it says.

Question doesnt vbulletin already cache templates?

Going to keep an eye on this one :)

Quote:

Question doesnt vbulletin already cache templates?

vBulletin caches the template in a state ready to eval, but they are still called from the database on every page, but not with vBO :)

Quote:

The query to fetch templates, and the query to fetch the style are both removed. The fetch user info query is the one with the chunk taken out, that chunk being the language/phrases since vB fetches that when fetching the userinfo.

this doesnt allow me to select styles :( the default style is the only always shown .. is that correct?

I'll check this out now, style switch should work, could possibly be a bug :)

Fixed, re-download and then re-upload the following file:
./includes/class_activecache.php

You'll be able to select styles correctly then :)

Just what i was looking for, thanks!!!! *Installed*

What extensions are you talking about?

Quote:

vB Optimise offers the ability to use alternative methods to caching if you have the extensions installed on your server, it is recommended you use one of these instead of File Cache.

If you have XCache or Memcache installed on your server, you can choose either one in the vB Optimise settings, and vBO will use that instead of File Cache, as both are much better than using the file system to cache data.

Do you still have to enable xcache in your config.php if you are enabling thru the mod?

XCache does not need to enabled through config.php, nor does Memcache, but the memcache server info does need to be included in config.php :)

So if I have it enabled thru config.php, should I comment out?

Not at all, you can use XCache in config and for vB Optimise, or use Memcache in config and XCache in vB Optimise, it won't conflict :)

Thank you kind sir :)

How well will this work with SEO or crawlers?

Won't effect either, this is purely improving performance. If anything I guess it means spiders won't add as much load as they used to :)

I get this when trying to flush the cache:

Fatal error: xcache_count() [<a href='function.xcache-count'>function.xcache-count</a>]: xcache.admin.user and xcache.admin.pass is required in /home/xxx/public_html/forums/includes/class_activecache_methods.php on line 161

good, at times i have 700 members online with about 900 spiders, i have to turn off my plugin/ hook system so my forum does not lockup. using a VPS server. we will see what this does in a week when i get slammed again

You should recieve a prompt when attempting to flush the cache asking for your username/password, this is because your XCache is configured to require an admin username/password when using administrative XCache functions. Is the pop-up for authentification not showing?

This can be disabled through your php.ini:

Code:

xcache.admin.enable_auth = Off

From what tests I've been able to do, the prompt should show on failure. It's possible the error haults this from happening, try the following change to see if it resolves your issue:

Open: ./includes/class_activecache_methods.php, Find:

Code:

                for ($x = 0, $total = xcache_count(XC_TYPE_VAR); $x < $total; $x++)

                {

                        if (xcache_clear_cache(XC_TYPE_VAR, $x))

                        {

                                $any = true;

                        }

                }

Change this to:

Code:

                for ($x = 0, $total = xcache_count(XC_TYPE_VAR); $x < $total; $x++)

                {

                        if (@xcache_clear_cache(XC_TYPE_VAR, $x))

                        {

                                $any = true;

                        }

                }

Find:

Code:

if (!isset($_SERVER['PHP_AUTH_USER']) && $x < 1)

Change this to:

Code:

if (!isset($_SERVER['PHP_AUTH_USER']))

Save and upload, let me know if this resolves the issue for you :)

Was able to get it using that workaround :)

Thanks. Didn't try the other lol.

No problem :) If you get a chance to try out the above changes to see if that works let me know how it goes.

I will, but I probably won't get the error now. Great work. Thank you. By the way, I am running RC1 and haven't upgraded to 2 yet.

Thanks for the note, it should run on beta installations of vB 3.8 too, but I won't swear by it :)

thanks works as promised

1 question -- when i try to flush, it asks me for xcache username and passwd, when i give the ones i have in php.ini file, it says wrong. wat are these username and passwd?

also vboptimize directory has only 1 index.htm file? am i supposed to 777 this dir so vboptimize can write some files here?

You need to specify your username and password for XCache, remember the password in php.ini should not be an actual password, but an md5 encrypted password, then you enter the plain-text password in the prompt. Otherwise you can disable the admin authentification for XCache, see a couple of posts above to see how.

As for vboptimise/, yes it should have read/write permissions, as specified in the Admin CP descriptions when you setup vB Optimise :)
