performance bench mark

| I just installed perlbal on my openSUSE 10.2 box, P4 2.8G, 512M RAM,
using ab to request a static file which is 12 bytes or so. The testing
result is not so good comparing with other web servers such as
lighttpd/nginx,
request num
concurrent num
req/sec
ms/req
ms/req(concurrency)
Kbytes/sec
10000 5 735.47 6.798 1.360 155.85
10000 10 772.32 12.948 1.295 163.65
10000 50 774.08 64.593 1.292 164.03
10000 100 743.55 134.489 1.345 157.56
10000 500 669.01 747.378 1.495 141.76
epoll was used by perlbal, and aio calling was not found according to
strace output, though I configured it through management interface. CPU
was very busy, 80% used for user space.
So, what's the main reason preferring perlbal to other web servers?

Are you missing the IO::AIO module?

With AIO correctly installed and configured it should be less.

Easy configuration? :-)
Actually - I think most of us use it primarily as a load-balancer.

Pretty much. I use it to serve static files, reverse proxy to my internal
webservers, and provide introspection on what is going on with traffic and
the like. The other features are nice to have too - reproxy, easy SSL,
header manipulation, plugin support, selectors, etc.
Sure, just about all of the above can be done with Apache or lighttpd or
some other solution, but in my experience the configuration of Perlbal is
the easiest and It Just Works.
