I have numerous remote sites using either PIX506 or ASA5505's connected back into a pair of ASA5520's over DSL connections.
Users at the remote locations are starting to complain about poor network access speeds. Compression is not currently in operation and I'm wondering if enabling it would make any performance benefits ??
Can anyone share their own experiences of enabling compression ? - does it work and if so did you see any noticable performance increase ?
Compressing the data can make sense especially with low speed links. As the previous posted said, make sure that it is compressing before encryption. Look at the documentation for the hardware that you have to see if the compression is done in hardware or in software. I would probably recommend doing it if supported in hardware at both ends of the link, but would only enable it in software if the link is really very slow or the bandwidth expensive such as dialup/satellite/GPRS/3G
