Benchmark questions

Hi,

I was looking at the benchmark section of the website
and got a few questions:

1) Is there any benchmark data for PHP performance at
concurrency higher than 1 (e.g. 100 or 400)? I noticed
from the static file benchmark that while the
performance of Apache stays relatively constant as
concurrency increases, the performance of lighttpd
tends to drop as concurrency increases. I wondered if
the same trend exists for PHP performance and that at
a high concurrency Apache might actually have a higher
performance than lighttpd, especially given the
relatively small edge in PHP performance lighttpd has
at 1 concurrency (25%)

2) The CPU-tuilization benchmark shows that Apache has
a higher throughput than lighttpd (e.g. at 1000 con,
100K files, Apache is 8258.31, lighttpd is 8096.55).
On the other hand, the static file throughput
benchmark shows lighttpd having much higher throughput
than Apache. What causes the discrepancy between the 2
benchmarks?

3) Has anyone looked at Lite Speed web server at
litespeedtech.com? Looks like it has similar
architecture to lighttpd. Anyone done any benchmark
between the 2 servers?

Thanks!

Andy
