What extra hardware resources on the web server are required?
The overhead imposed by pageVault on a typical web server environment is very small, and typically no extra hardware provisioning is required. Unless the machine running your web server is very heavily loaded, you should notice very little if any response time degradation with pageVault, because the CPU and memory loads imposed by pageVault on most requests is very small. Basically, the main CPU load is the calculation of the checksum of the response, which is a very efficient operation. As little processing as possible takes place in the critical path of generating the response to the user. The pageVault distributor, which typically runs on the same machine as the web server, can run at a lower dispatching priority than the web server and will generally consume few resources and only then when many unique web responses are being generated. The typical web server spends most of its time sending responses it has sent previously, and the overhead of pageVault in these circumstances is ve
