SigmaWeb is a medium-sized Greek hosting provider with a sterling reputation. ("Search on Google," Stratos, the owner, will say. "You won't find a negative comment.") They provide both shared and dedicated web hosting, domain registration, and web development services, but SigmaWeb had generally avoided the high-traffic market until recently.
Then they were approached by the owner of two popular WordPress sites — seriouslyforreal.com and sarcasticcharm.com. The customer had been disappointed by a few well-known hosts, and the challenge was daunting: the two WordPress sites average of 80,000 unique visitors/day and about 70 requests/second for a total of about 1,000,000 page views/day . SigmaWeb set them up trying first with Apache 2.4.6, then Apache 2.2.25. The load numbers, though, showed these Apache setups weren't going to cut it — especially since the customer planned to run a promotion that would increase traffic further.
"At that point, my old friend Jones, from JoneSolutions.Com, tells me: 'Only LiteSpeed can do the job for this project.'" Stratos tested a trial license , then installed a 4-CPU license via LiteSpeed's cPanel plugin. It was Stratos' first experience with LiteSpeed, but installation only took a few minutes. The difference was remarkable:
Load dropped from 8 (with spikes to 12) down to below 1. Memory usage dropped from over 14GB to below 4GB. LiteSpeed's event-driven architecture (and optimized code) were dramatically dropping the number of processes the system had to run, from 150-200 with Apache to under 10 with LiteSpeed Web Server.
Since switching, the site owner is ecstatic — they've found their host — and Stratos is happy as well: "I have been in the hosting business since 2003 and tried various solutions, like nginx. This is the first time I've seen something like this. Thanks to LiteSpeed Web Server, I will seriously consider entering the heavy-traffic market here in Greece, a market which I had been afraid to approach. Congratulations. You guys have done a great job!"
