I don't but you may be able to get quite a bit of improvement using the inflateBack, inflateBackEnd, and inflateBackInit_ functions.  The one I use is based on  the "Enhanced zlib package" from Borland's Code Central (entry ID: 23490) which I then modified for Indy usage and modified so that you can use it in FreePascal.  I tested it with an example program in Linux and Win32.  If anyone wants to test what I have, please feel free to do so and may be the best code win.

It is part of the source-code downloads that I made last night.  The URL is http://www.indyproject.org/sockets/fpc/.
