[Zlib-devel] Any plan for optimized versions for recent x86_64 architectures?

[Vincenzo Innocente]

    Dear All,
we are looking to way to speedup compression and decompression for our applications where we use zlib. We run essentially only on linux x86_64.

I've noticed that in recent Linux distributions optimized version for sse2, sse3 and sse4.2 as has been contributed to glibc for string functions such as strcmp, strchr etc which are used by default.

 Does anybody  know if  there is any plan to officially support optimized version of libz on x86_64 architectures using sse (including sse4.2) instructions?
Any development going on that we can test?
Any additional hint you can give us about speeding up zlib, even specifically on Linux running on recent Intel/amd x86_64 cpus, will be appreciated.


   thanks,
  Vincenzo Innocente
