Poul-Henning Kamp, a well-known FreeBSD developer who participated in the creation of systems like MD5crypt, GEOM, GBDE, and FreeBSD Jail, has announced the release of Varnish-Cache 8.0, a high-performance caching proxy intended to act as an HTTP accelerator. The project is distributed under the BSD license and has been used in projects by Facebook, Wikimedia, Twitter, Vimeo, Tumblr, The New York Times, and The Guardian. <\/p>\n

High performance is achieved through the use of multithreading, connection multiplexing via epoll\/kqueue calls, and the implementation of system calls like sendfile and madvise. On standard hardware, it can handle a throughput of 20 Gbps and accelerate request responses by 300 to 1000 times. The cache is stored in virtual memory. A distinctive feature of Varnish is its ability to assemble delivered pages in parts on the frontend, determining the assembly logic using the ESI (Edge Side Includes) language. <\/p>\n

Varnish also provides a flexible configuration system that allows for the use of inserts in the C language. A special VCL language is used for configuration, which is then compiled into executable binary code. VCL allows for defining request handling policies: specifying the content to be handled, where to obtain it from, and how to transform it before delivery. Basic functionality can be expanded through modules. Load balancing, state tracking, and backend response time mechanisms are present.szerverek<\/a>. <\/p>\n
