Once again my many thanks to Joshua for providing concise and extremely informative responses on this list.
Joshua; Its people like you that make open-source communities *work*. Cheers from Calgary, Chris Price
Plenty of people use mod_deflate (and the older mod_gzip), so there isn't any big catch. It does indeed significantly reduce bandwidth usage and sometimes latency. There are some disadvantages: - Browser incompatibilities. The mod_deflate docs give instructions on how to work-around the most common ones.- Increased processor usage. But many webservers are not processor constrained.- Pages become less cacheable since you need to vary on at least accept-encoding, and frequently user-agent as well. - You can't use zero-copy techniques (liek the sendfile syscall ) to send files, which increases the load on the server. - For many sites, the majority of content is already-compressed stuff like images, which won't be helped by mod_deflate.
