The ISP hosting a mostly static web site complains when certain users start to hammer the site at around 30 hits/second. The machine slows to a crawl, apparently. The files can be simple pages with a few graphics, to fairly large files. There are other sites hosted on the server, so this is not good news.
Should Apache be able to take this load? Are there tips that the ISP can use to tune the server for this? Is there anything to tweak on the pages themselves?
