 > The [current version of OpenFaaS templates](https://github.com/openfaas/templates) use the original `watchdog` which `forks` processes - a bit like CGI. The newer watchdog [of-watchdog](https://github.com/openfaas-incubator/of-watchdog) is more similar to fastCGI/HTTP and should be used for any benchmarking or performance testing along with one of the newer templates.
