Just to clarify, those numbers are requests per second, bigger is better.
The initial tests A and B used OpenSSL 0.9.6, and C used 0.9.5a.
I just ran through some tests on our SGI machine with
Apache/1.3.12+mod_ssl/2.6.6+OpenSSL/0.9.6 vs
Apache/1.3.12+mod_ssl/2.6.6+OpenSSL/0.9.5a (Basically OpenSSL 0.9.6 vs
0.9.5a).
It appears that OpenSSL is responsible for the large performance difference
between the different versions. It seems that all Apache/mod_ssl builds
with openssl 0.9.5a report around 90 requests/second while the same build
increases throughput to around 150 requests/second.
This is on a dual-processor SGI Origin 200.
I don't know if this performance difference exists on other architectures,
but that huge performance boost with just openssl 0.9.6 is great!
