What webserver are you using?
Litespeed is great and Ngix too.

Btw, That FORUM would make tons of money from adsense :D

I prefer Nginx. With the money I save from Litespeed Enterprise license, I put another grand on top and buy a very good server. :)

I use good old Apache 1.3 :)

We are having 5 web servers and 1 db for our board.
Our board generates about 20+M pageviews/mth with approx 1300 - 2500 users online (as reported by vB on a 900 secs timeout)

However, the access is pretty slow and recently our db load is very erratic. It can jump to 100!!!
Refer to http://www.vbulletin.com/forum/showthread.php?p=1485653

Anyone can share with us on how to optimize our setup? Our servers are installed with off-the-box RHEL4. We do not have knowledge on how to custom build kernels or modules.

Apparently that way seems to be the most efficient to keep load down and serve out fast.
Anyone can share where to find such info.

For those who indicated 2 dbs, how is your setup like? How to have 2 dbs in 1 vB installation?

It's hard to say without deep into servers..

Server can handle much more than above needs, it's on light load now.

Sorry but that is simply not true.

Load is essentially "processes in queue". 1*cores load means all works in about realtime. To interpret any loads higher than that is not that straighforward. What those processes are, are their queuing really slowing things down, how long do the queued processes need to execute etc?

Wow,

that is impressive.

Would you mind share us your config for Litespeed? i have a board with that much of member online but less post and thread. Running on Xeon 5335 with 4GB of ram and 73GB SCSI for both webserver and database.

But at peak it low down.

Thanks

I can see this. I can't believe the load difference since we switched to a SAN. I would think NAS would have the same functionality. It really seems to be all about the drives. I'm not about to try it but I bet I could get away with not having seperate front end servers.
