High Availability and High Performance

Liferay Portal has been tested to support more than 3,000 concurrent transactions (33,000 simultaneous users) on a single 8-core application server, with mean login times under one second and maximum ½ throughput of 79+ logins per second. Our Web Content Management (WCM) system scales to beyond 150,000 concurrent users on a single Liferay Portal server with average transaction times under 50ms and 35% CPU utilization; In high-traffic web-publishing scenarios, Liferay Portal has proven to handle millions of page views and over 1.3 million users. Additionally, in collaboration and social networking scenarios, each physical server supports over 1300 concurrent users at average transaction times of under 800ms.

Liferay Portal is also deployable to the Cloud and virtual server environments and ensures high availability and performance with:

• Hardware/Software Load Balancing, HTTP Failover, Session Replication

• Distributed Cache using Lightweight Multicast Protocol

• Terracotta, Oracle RAC, and other scalability solutions
