I finally managed to disable compression, and the performance improvement is dramatic. Now I have "only" 100% penalty for using SSL, as seen in this oprofile report: samples % image name symbol name 751 50.1670 libcrypto.so.1.0.0 /usr/lib64/libcrypto.so.1.0.0 594 39.6794 postgres hex_encode 83 5.5444 libc-2.12.so memcpy I'll post to hackers and see if I can get this into core.
