Re: How many concurrnet user does review board support?How to setup Apache load balance for it?

2010-06-01 Thread Christian Hammond 
Hi,

If you're seeing things fail past only 5 concurrent users, there might be
some configuration problems on your server. We know of servers with several
hundreds of concurrent users without failures.

Can you tell me a bit about the specs of your server? How many CPUs, what
speed, and RAM size?

Are you using memcached for caching?

At what point are you hitting issues? What pages?

Setting up Apache for load balancing is a bit beyond the scope of this
mailing list. There are lots of howtos out there for load balancing Apache.
It should work just fine with Review Board instances.

Christian

 hi All
 Do you do performance testing for reviewboard? How many concurrent
 user does review board supports? I do performance testing for
 reviewboard (mysql5,reviewboard1.0.8,clearcase), it only supports 5
 concurent user.

 If i want to setup Apache load balance for it, how can I do it?

You really need to be more specific.

Please define these terms:

   - supports (what do you see that implies does not support?)
   - concurrent users (is that simultaneous requests or total userbase? --
   5 simultaneous requests actually represents a much larger userbase)


In my environment, I have orders of magnitude larger userbase than that, but
Mysql tuning may be required for you to get there along with memcache or
some other caching strategy. Also, how many Clearcase licenses do you have?
Are you running into a licensing problem on the back-end  to your revision
control system?
