I'll be surprised if anyone is able to provide an authoritative answer here. There are a number of factors that contribute to how PHP performs in a given environment. You may just have to benchmark it. That said, I suspect that using PHP to gzip the stylesheets will yield a faster page-load time than not compressing them at all, given the file-sizes you describe. > I can try and get a few tests running but I will hold off in case anyone > here knows already. Please do share the results if you elect to perform benchmarking. I'm curious :).
