Web accelerators may be installed on the client (browsing) computer or on ISP hosted servers or both. Accelerating delivery through compression requires some type of host based server to collect, compress and then deliver content to a client computer.

As of June 2005, these applications generally serve to improve [[dial-up]] and other low speed connections. Many users can achieve a 2 to 3 times speed increase in average browsing experience, while some report a 5 to 10 times speed increases for specific web pages. Many ISPs offer web accelerators as a part of their dial up service.

Artera Turbo and [[Google]]'s [[Google Web Accelerator|Web Accelerator]] hashave attempted to improve [[broadband]] access to the sites. Moreover, they are designed for web browsing and, sometimes, for e-mailing and can not improve speeds of [[Streaming media|streaming]], gaming, P2P downloads or many other Internet applications.

*Google requires the download and installation of client software while Artera Turbo is entirely network-based (no end user software component).

*Perhaps more importantly, while both offerings increase end user speed, the techniques used by Artera Turbo reduce the amount of bandwidth ISPs need to pay for (resulting in net cost savings) whereas Google tends to increase bandwidth requirements (resulting in net cost increases).

Some web accelerators have been very controversial pieces of software. Critics claim that prefetching HTML page links slows the internet backbone. Others suggest that the accelerators overload web servers with prefetching and cache freshening behaviors.
