I've just added support for the LZO compression algorithm[0], though minilzo, in gnutls-extra library. The results are quite impressing, and in some cases the lzo algorithm is faster than the null compression. Check http://members.hellug.gr/nmav/tls-comp.html for a preliminary comparison of zlib, lzo and null. [0]. http://www.oberhumer.com/opensource/lzo/ -- Nikos Mavroyanopoulos mailto:nmav@gnutls.org
