Subject RE: [PATCH] mod_deflate extensions
Date Tue, 19 Nov 2002 14:13:16 GMT
Since when does web server throughput drop by x% factor using
mod_deflate?

We went through this debate with mod_gzip and it doesn't hold much
water. Server boxes are cheap and adding some more ram or even a faster
processor is a cheap price to pay when compared to customer satisfaction
when their pages load faster.

If mod_deflate is doing it's job correctly then compressing a page even
if it's a 100K should be in the microseconds. Transmitting 80% less data
will be reflected in the web server performance as it returns to work on
other connections.

when you drop the web server throughput by x% factor you may make
yourself sad :)

I wish it were so simple as finding a zlib, but static zlib
distributed with some OSs vs dynamic zlib distributed with others
seems to be the difference between success and failure.

I definitely agree that it would be nice to turn on mod_deflate in the
build automagically, I just don't want to do it at the expense of more
problems encountered by users.  I suspect that we would need to ship a
subset of zlib ourselves in order to have a fool-proof build of it.
