Have you run system profilers to see where the bottlenecks are? You
can do this when the system is moderately loaded, it will give you an
idea what problem will hit when the load goes up.

Hi, Guys
Our team is running a web2.0 finance site in China
<http://www.caibangzi.com/>http://www.caibangzi.com/
We use APACHE + mod_proxy_balancer + mongrel to deploy our
application, it workd super in the past few monthes.
However, just from last week, at high traffic hour (about 40,000
request per hour), our site is very very slow, it usually took more
than 10 seconds to get a page or simply return timeout error.
I telnet to the server and found that when I visit directly to one
mongrel instance, it can return shortly, however when I visit from
apache interface, it hang.
I also cannot visit (timeout) the mod_proxy_balancer's frontend to
see the balance-manager.
However, the server load is just normal :(
We guess maybe the reason is slow action block mongrel, is it the
reason? Have any of you experienced of this?
Any comments are appreciated.
Our Server:
Dual-Core AMD Opteron(tm) Processor 2214 HE * 2
4G RAM
20 mongrel instances
mysql
