Sever size
 

I notice that even though there are a bazillion people on line at this site, it flat screams as far as speed.

Can someone tell me what type of server this site uses?
Ram, CPU, etc...

My site is bogging with only 100 online users. I am using a clean vb 3.87, with no mods.

Are you on a dedicated, VPS, or shared server?

Started with shared at A2Hosting and blew by that within a few minutes. Upgraded to their VPS+.

They tell me that my mem usage is peaking at 3 gig and according to them, that's the max. I'm thinking 3 gig? I have 5 year old laptops with more memory. They are suggesting a dedicated server but are telling me that it's only 4 gig, and it cost $200 per month (an extra $120 over the VPS rate) . (ouch)

Even if I was to try and swallow that $200/mth charge, if I am peaking at 3 gig, I doubt one more gig will help.

Maybe it's time I went back to using my own server co-lo'ed somewhere... it has 64gig ram.

Are the 100 users all members, or are alot of them bots?

Please provide site URL?

There is other hosting out there with better servers i would think about moving if the one u are on cant handle what u have now

All members... I do have guests but they are limited to one small category/forum (of 175 different sections)

xRunner bots are non-existant, I turned off new registrations.

No, by bots I mean search bots.

fyi: Up until a week ago, I had a very old highly customized version of Invision but it started showing signs of age (over 10 years old) so I converted to vBulletin - I am running v 3.81. I bought and could upgrade but I like the look and feel of 3.x so I stuck with it and did not convert to 4+

122,000 members, 2 million posts (2 more million waiting to be uploaded from old system)

With the old Invision software, it had a few issues (terrible search, lack of mobile skins, etc) but it was very fast... at least until it started mySql issues a week or so ago - thats when I converted to vb and, thats where I am today... a slow server on a completley clean no modded VB. (ok, not completely no-mods - I did add some adverstising on the side and top but those are not the issues slowing down the site).

dunno... I need to monitor those and disable them as muich as I can (I assume via robots.txt?)

First byte time from your host is terrible.

You can repeat this test and also run it from different locations, different connection types and browsers, and so on.

You have one 404 error in your waterfall, apparently a missing image.

As you can see by the waterfall chart, once the "handshake" between the server and the browser is finished, your vBulletin then loads in less than one second with only 584kb of data loaded and only 47 requests.

The issue the host is reporting has nothing to do with your vBulletin installation, it has to do with them overselling this machine it is on.

Get a responsible host.
