Line 21: ==Web client accelerator== Introduced in 2001-2002 [[https://www.wsj.com/articles/SB106012229328087800]], these applications generally serve to improve [[dial-up]], [[broadband]] and other connections from which users may not be getting the best speed. Many Dialup ISPs offer web accelerators as a part of their services. The pre-compression operates much more efficiently than the on-the-fly compression of V.44 modems. Typically, website text is compacted to 5%, thus increasing effective dialup throughput to approximately 1000 kbit/s, and JPEG/GIF/PNG images are lossy-compressed to 15–20%, increasing effective throughput to 300 kbit/s. The drawback of this approach is a loss in quality, where the graphics acquire [[compression artifacts]] taking on a blurry or colorless appearance. However, the transfer speed is dramatically improved. If desired, the user may choose to view uncompressed images instead, but at a much slower load rate.
