I just install and I don't see it anywhere.

Having performance issue with SQL , for big forums its not good , will you think optimize it for big forums?

Sorry but just saying "performance issue" and "optimize" are not really very useful. Define exactly what your issues are, and what you mean by optimize.

Well we are running lighttpd 1.4.19 with php 5.2.5 + mysql 5.0.51 + xcache 1.2.2 + memcached for data storage before installing your mod our MySQL usages were max %35 CPU usage , php-cgi usages max %20 CPU usage on system after installing it MySQL usage increased to %89 cpu and php-cgi increase to %70's!... but we need this mod so decided to increase our hardware added 2gb ram and changed mysql config to mysql-huge + tuned with mysqltuner now its better no huge loads... we were using mysql-large + tuned with mysqltuner and mysql was having %10 slow queries :/ ...
For big boards i can just say this upgrade your hardware...
Now our hardware:
AMD Athlon(tm) 64 X2 Dual Core Processor 4600+
4 GB Ram
250GB Raid5 Disk.

What size is your forum ? What settings are you using for the mod ? I run this on a forum with over 1 million posts, with a years worth of data, no time limit and some threads have over 1000 members who have viewed them, but its not causing any issues at all.

good work. . .

Does this hack work with 3.7.0 R C 4 ?

I want this in one forum area ONLY. Can this be done ? Like this changes ?

Hi Paul... yep me ahgen LOL I have installed the 3.7 version on my 3.7 board but the whowhere is not showing.

I don't get any errors and the show users browsing is on.

Could it be the template edits didn't take? and if so, can I manually add them or???

Thanks in advance.

There are no template edits as such, its auto added at run time.

Any ideas on what is causing it to not show? Thanks in advance.

FYI-- I did a template search for this code <!-- end currently active users --> and I don't see any addition to code that relates to this mod. Is there suppose to be code automatically added here?
