Please help editing this wiki. Thank you. |

| * AdvancedPageReplacement - brainstorming on how to implement advanced page replacement algorithms in Linux. * SwapTokenTuning - the current implementation of the swap token logic is essentially a proof of concept; there is a lot of room for improvement. * [http://linuxcompressed.sourceforge.net/ Compressed Caching] reducing the amount of disk IO that Linux has to do, by compressing currently inactive pages in the page cache. This project has kernel patches available and interesting performance numbers... * VmTrace - a kernel patch and tool to analyze memory access patterns. == Links == * [http://lkml.org/ Linux-kernel] mailing list * [http://bugzilla.kernel.org/buglist.cgi?short_desc_type=allwordssubstr&product=Memory+Management&bug_status=NEW&bug_status=ASSIGNED Linux MM bugs] in the kernel.org bugzilla * KernelNewbies:KernelNewbies a community dedicated to studying the Linux kernel, also see the [http://kernelnewbies.org/ Kernelnewbies web site] * [http://linux-net.osdl.org/ LinuxNet], a wiki on the Linux network subsystem == News == * See MemoryManagementNews * 2005-04-22, over the last few days, I wrote down everything I knew about AdvancedPageReplacement - I'll use this wiki to keep notes while implementing code (RikvanRiel) * 2004-12-19, created this wiki, started moving some content across from the old site.
