There is a reason why people install Varnish Cache in their servers. It’s all about the performance. Delivering content from Varnish is often a thousand times faster than delivering it from your web server. As your website grows, and it usually grows significantly if your cache hit rates are high, you’ll rely more and more on Varnish to deliver the brunt of the requests that are continuously flowing into your infrastructure.
Unlimited cache sizing, increased caching performance and customized cache optimization support content-heavy, high-traffic sites. Varnish Software is pleased to officially announced the release of Varnish Massive Storage Engine, Varnish High Availability and Varnish Tuner. These three components are designed to support the scalability and performance needs of content heavy, high-traffic websites and are now available as part of our Varnish Plus offering.
Following up on the test of dmcache we decided to scale it up a bit, to get better proportions between RAM, SSD and HDD. So we took the dataset and made it 10 times bigger. It is now somewhere around 30GB with an average object size of 800Kbyte. In addition we made the backing store for Varnish ten times biggers as well, increasing it from 2GB to 20GB. This way we retain the cache hit rate of around 84% but we change the internal cache hit rates significantly.
The results where pretty amazing and shows what a powerful addition dmcache can be for IO intensive workloads.
