Worse DeflateStream decompression speed than System.IO

Mar 26, 2010 at 12:05 AM

Hi-
I really like this library and the options for specifying compression levels, strategy, and buffer size.  However, I was a bit surprised when I discovered that decompressing my files was taking about 1.7-2.0x the amount of time using the Ionic.Zlib.DeflateStream than using the standard .NET Framework 2.0/3.5 SP1 DeflateStream.  My files are relatively small -- <1 MB each.

Is this an known issue here or does anyone have any ideas of why I might be experiencing this?

Thanks

Hm, I haven't benchmarked the decompression.  I spent some time benchmarking, profiling, and improving the performance on compression, but not on decompression.

So it's not a known issue.  I find it slightly surprising, but not shocking.
