"One of an e-business' most valuable assets is its Web server. For an enterprise looking for room to grow, Zeus claims to be the best choice. Zeus does have a track record in this regard, being the main Web server used by eBay, Lycos, Infoseek, and Blue Mountain. It also claims to host one out of every 35 Web sites...."
"Apache uses a dedicated I/O process for each connection request. This might not be such a bad thing if an infinite number of connection requests could be created, but that isn't the case. Apache is limited to 256 connection requests. Zeus uses a small number of processes, but each process can handle, as previously noted, tens of thousands of connection requests. Even one Zeus thread can handle many more connection requests than Apache as a whole."
"One should bear in mind that Zeus' capabilities do not really shine unless there are a large number of connections. Thus, administrators will not really benefit from Zeus over Apache unless they have high traffic volume. That is why eBay, one of the most heavily trafficked e-commerce sites, uses Zeus. Zeus runs rings around Apache in terms of serving massive amounts of traffic."
