General performance of perlbal

[Mika Vatanen]

Hello,

I have been trying perlbal installation but have experienced very high
CPU usage and poor performance numbers. The maximum performance obtained
has been around 150 requests / second measured by apache bench on a
2.5Ghz Celeron box. According to strace, perlbal uses epoll but still
gets CPU bound.

What are the possible requests/s numbers that perlbal could handle if
everything worked well? Any ideas of what could be the problem and how
could it be fixed?

Thanks!
