There are some extracts from the 2007 O'Reilly Tomcat book about benchmarking
on somewhat newer hardware than Chris is using:

Actually, I was thinking more of disabling the AccessLog in httpd, to
see how much impact that had.
(That's also less additional tests to run ;-))

Thanks for the work. At least it may put to rest some gross misconceptions.
Now just a question : in the httpd tests, did you have an AccessLog
enabled ? I would imagine you did not have an AccessLogValve enabled in
Tomcat, and I wonder if it makes any practical

Quantum mechanics?

I'm a bit puzzled:
In your previous tests it looked like that Apache is "outperforming"
(ok, not really) Coyote w APR when the files grew bigger.
In your last results I can't see that pattern - actually, I don't see
/any/ pattern...
Any idea how come?

All,
So, I have some data from last night. It's about what you'd expect,
except that the NIO+sendfile connector test failed most of the time: the
client got something like "apr_connect: Connection reset by peer" when
it tried to connect to the server.

They are transfer Rate (KiB/sec) as measured by ApacheBench.

Chris, what do the numbers represent ?
You say you ran each test for 10 seconds, so I guess the numbers are not
the seconds it took, so what are they ?
I also wonder about the numbers, for example in the first column
(httpd). They seem to grow more or less lineraly as the file size
increase

As a rough first cut, vmstat 5 and watch the numbers ;-). iostat too, if you
can. If CPU isn't pegged at 100% and the disk isn't at full capacity, that's

All,
Last week, I decided to actually run my own performance measurements.
Before I waste a lot of time benchmarking, I wanted to vet my
methodology so I get all the data worth taking.
I'm using ApacheBench 2.3 (ships with httpd 2.2.10) as my benchma
