Nexcess Announces Update to Turpentine Varnish Caching Extension For Magento

Southfield, MI – Nexcess, the industry leader in optimized Magento hosting and a Magento Platinum Hosting Partner, has announced the release of a major update to the Turpentine Magento extension, which further improves integration between Magento and the Varnish caching reverse proxy.

Turpentine, an open source Magento extension developed for use on Nexcess’ optimized Magento hosting platform, enhances the performance of eCommerce stores by modifying Magento’s behavior to improve compatibility with Varnish, increasing the effectiveness of Varnish’s caching for the eCommerce application.

Version 0.6.0 makes Turpentine compatible with the most recent versions of Magento, including Magento Community Edition 1.8 and Magento Enterprise Edition 1.13. The update also includes numerous feature enhancements such as Magento Composer Installer support, lurker-friendly bans, and fixes for issues affecting ESI cache flushing and the caching of static assets.

Varnish is an HTTP accelerator that sits between Magento and the Internet, caching data from the eCommerce store. Implementing Varnish caching for Magento can significantly improve responsiveness and performance, but without Turpentine, Magento cannot take full advantage of Varnish’s caching capabilities.

Turpentine modifies Magento behavior to enable full page caching, even for logged in visitors. The extension supports multiple Varnish instances for clustering, automatic cache clearing, and cache warming with a built-in site crawler. Turpentine can also generate and apply new Varnish configurations (VCLs) on the fly.

“We’re proud of the significant progress we’ve made with Turpentine in the 18 months since its initial public release,” commented Chris Wells, President and CEO of Nexcess, “Along with our optimized Secure Isolated Platform servers and Magento clusters, Turpentine contributes significantly to our ability to satisfy the stringent performance requirements of Magento users.”

Nexcess designed its Magento hosting platform to provide eCommerce retailers with unbeatable performance, responsiveness, and availability. In addition to Varnish caching, Nexcess’ Magento servers are optimized throughout the stack and include performance-tuned Percona databases stored on 15K SAS drives with RAID 10 filesystems, fully optimized web servers with PHP-FPM and APC (Alternative PHP Cache) for fast execution of the PHP-based Magento application, and enterprise networking infrastructure based on Cisco Catalyst 6500 series equipment, fully burstable 1000Base-T connections, and redundant connections to four bandwidth providers.

Turpentine is released under the GPLv2+ open source license and is freely available to developers and users.
