Mach5 Analyzer is for you if you have a successful Web site that gets a lot of hits every day. You love the traffic, but the log files are another thing: they are enormous and take hours for your current log file analysis tool to process. Yet your advertisers demand detailed information about who is visiting your web site, where they come from, and what they visit. You need a log file analysis tool that gives you over detailed information about your web site, but one that does not take hours and hours to run. FastStats can speed through your web server log files at over 100 times the speed of WebTrends and HitList.
