Neil, >Anyone using Content Compression with any of their sites/apps (on the fly >or >otherwise). If so, what are you using what kind of speed improvements are >you getting if any? I am particularly interested in IIS implementations.
Performance improvements are going to be relative to your app and your servers. If you're pages contain lots of HTML overhead (which can happen to apps that rely heavily on <table /> elements for layout) then you could see a sizable difference in the bandwidth needed to xfer your output from the server to the client. On a recent project I migrated an older application that tends to be very markup heavy to a new server. It's not uncommon for it to produce pages that are 100k+ of markup. Using IIS6's native compression has drastically help us reduce the bandwidth needed to xfer these files, which does make some of the larger reports on our page appear to load faster. However, it's important to notice that compression does not really give you "speed improvements." It actually adds more processing time to the request (while for dynamic content--since it needs to be recompressed on every page request.) However, it can help drastically reduce the amount of bandwidth need to transfer files to the client. In our situation, the time that it takes to compress most pages is barely noticeable and the gain in delivery time far outweighs the additional overhead. I can't qualify these into real numbers (partly because the migration to new servers also meant migrating to faster servers,) but in my testing there definitely was a significant decrease in delivery times after applying compression. If you're paying for bandwidth usage, compression can also help reduce your hosting costs as well (or at least allow you to serve more pages than before.) -Dan ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| ColdFusion MX7 by Adobe® Dyncamically transform webcontent into Adobe PDF with new ColdFusion MX7.
