The following is a lot of information about a specific performance
tuning related problem I am having with a LAMP web server. I'm not sure
if this group is appropriate for such discussions, please advise if
otherwise.
I'm having a performance problem with a php web application that is
hitting a performance ceiling at 34 pages per second with no obvious
bottleneck.
I've factored out calls to the database and used the loopback device for
this test.
My basic premis is this:
During testing there appears to be 50% of CPU resouces in idle state,
with most dedicated to user, some in sys, and almost non in iowait
states. This tells me that I should have room to process more
concurrent requests without adversely affecting the response time of the
web application. Unfortunately, this is not the case- as I increase the
number of concurrent users during subsequent testing, the pages per
second remain the same while the average response times grow larger.
This tells me there is indeed a bottleneck, and based on the output from
vmstat and iostat I am hopeful it is not a bottleneck based on hardware
saturation.
One thing interesting to note that I'm not sure if indicates a problem
is that I have ~ 3 times the number of context switches (3000) than I
have interrupts per second (1000.) Since cpu sys utilization is so low,
I am assuming this is not a problem.
I've also included a dump of my sysctl settings in case there is a
problem with tunable parameters.
The environment is mod_php 5.2.1 with apache 2.0.52 running RHEL 4.5
(2.6 kernel) on an Intel Xeon 2.4G Dual Core with 2G ram and a SCSI raid
5 and 1Gb NIC.
The following data was captured during a stress test. It includes
output from apachebench, vmstat, iostat, syscntl and httpd.conf for a
period of one minute.
I'm hoping someone can take a look and offer some suggestions on
potential bottlenecks that I have overlooked.
Thanks.
