If it doesn't give you any performance improvement then you haven't
disabled compression. Modern CPUs can easily saturate 1 GbitE with
AES256-encrypted connections. Compression is usually the bottleneck,
at 20-30 MB/s.

Hmm, my knowledge of OpenSSL is so little that it is well possible that
I did it wrong. I have attached the small patch I used; can you see
where I went wrong?

That only works with OpenSSL 1.0.0 - did you upgrade? I thought you were using 0.9.7a earlier.

FWIW, it would be better to test "#ifdef SSL_OP_NO_COMPRESSION" directly, rather than the version number.
