Thanks for the references and your insights. I will give some of these ideas a try and see how it works out for me. ====================== Jeff Shearer, CISA, CISSP -----Original Message----- From: "Tom Evans" [tevans.uk@xxxxxxxxxxxxxx] Date: 01/31/2011 04:33 AM To: users@xxxxxxxxxxxxxxxx Subject: Re: compression on hard disks On Mon, Jan 31, 2011 at 12:06 PM, Rich Bowen <rbowen@xxxxxxxxxxx> wrote: > File compression and decompression happens within your operating system, and Apache doesn't care.

So apart from the performance hit in decompression, it doesn't notice at all. It also means that no, it can't pass that compression through to the client. It can, however, recompress it using mod_deflate. > > From a website performance perspective, compressed filesystems are a bad idea.

Compressed filesystems are a bad idea for serving files from. However they may have other uses; I use a lzjb compressed /var/log partition on ZFS, and that is quite handy from a performance POV.
