Hi Joe,
>1) Apply this patch: > http://goochfriend.org/pound/pound_2.6_SNI_Optimization.patch to prevent some > possibly unneeded SNI checks in SSL handshakes I´ve just made a test with the mentioned patch, but there is no difference in the behavior of the loadbalancer. 2) Investigate and change your Threads value. The default of 128 may be > your limiting factor. Experiment with more or fewer threads to determine > the best trade-off of performance and memory. Where can I change it ?
