The more ports we have - the better code we get.
I.e. port is definitely useful.

I never trust benchmarks which haven't run on my own, but slide 8 here:
http://www.slideshare.net/Hadoop_Summit/kamat-singh-june27425pmroom210cv2
is a good fit regarding cpu time vs. compression ratio.

Is anybody interesting in have mingw support in Firebird? Or it will be
only in private repos around internet.

Has anyone done any performance studies on zlib? Decompression is OK, but
compression is very, very CPU intensive. I did a study a while back to
investigate using zlib for blobs. The short answer is that it was much,
much faster to read the extra pages than pay for zlib compression and
decompres

Have you guys considered LZ4? https://code.google.com/p/lz4/
It is getting very popular in the big-data / NoSQL area for both,
compressing data on disk and over-the-wire.

IMHO, client and server should handle cases when zlib is not found and
ignore

Hi all.
Recently wire compression was implemented by Alex. It uses well known zlib
library. On Linux zlib could be installed as a standalone package and there
is no problems with its presence nor for Firebird users, nor for those who
going to build Firebird. But on Windows i found no common
