mercatum™: Technical Data
mercatum™ currently runs under Java 1.5. A typical set up will use Linux, the Apache HTTP server, Tomcat (the glue between Apache and Java), and PostgreSQL for the database. Using high quality open source software enables us to provide our clients with stable, scalable systems at very competative prices.
For high-availability, high-performance, we offer a postgresql database cluster that allows you to scale your mercatum installation to very high levels of user visits.
mercatum™ is designed to make very effective use of caching; keeping pages in RAM minimises the need for the significantly slower process of reading from hard disks, especially when they are frequently viewed. It also reduces the hit to the processor for pages that do not need to be re-evaluated each time they are accessed.
