Summary Websites that wither under pressure from the slashdot/digg-effect more often than not use the status-quo Apache web server. Apache is the stable market-share champ from Apache foundation (www.apache.org) that is showing its age and has not enjoyed an evolution performance upgrade in decades: simply perform some benchmark search queries on Yahoo/Google and one will find that Apache 2.0 is barely if at all faster than Apache 1.3 it replaces. When it comes to performance and scalability, LiteSpeed is rightfully proud to proclaim that Apache is not in the same league.
Based the highest performing programming architecture, asynchronous event-driven model, LiteSpeed Technologies has created a world-class web server that not only breaks the status-quo when it comes to previously accepted performance/cost benchmark but also aspires to set a new standard where other web servers are compared to.
* Based on benchmarks performed by LiteSpeed Technologies. Do not just trust our word for it, perform you own benchmarks and prepare to be pleasantly surprised.
