Hi,

I’ve just been comparing the performance of stunnel on Solaris 10 & Linux (Centos 5.5) and am seeing a big difference. I’m using stunnel 4.33 compiled with the same options on both platforms and the tcpstress benchmarking tool (http://stunnel.mirt.net/?page=perf).

On a Dell 780 running Solaris 10 I got 163.31 connections/second but on an older, slower Dell 620 running Linux I got 408.01 connections/second. Both machines were otherwise idle.

Does anyone know why there would be such a big difference between the two OS’s?

Thanks,

Steve.
