Hi Stephen/Michael.
for the configuration settings, I would suggest you use:
AddoutputfilterbyType text/html  DEFLATE
as compressing css & js files breaks certain browsers (I believe)
this will give you the most bang for buck so to speak.
you may want to change the defaltememlevel to 6 and see if you get the
same compression ratio that mod_gzip does.

one of the other design decisions made was to keep the code simple, and
we used zlib instead of including our own custom compression code, which
may also explain why mod_gzip is getting better results.

|     DeflateWindowSize 15
|     DeflateMemLevel 9
|     DeflateBufferSize 8096
|

| mod_gzip I am running at the default level of 6.

| If anyone can think of a way for me to tweak mod_deflate (yeah, I know;

| be appreciated.
