Hey all, I just read a document with the idea for changes in page cache management for 64 Bit machines. This has been taken from Linux symposium 2006, ottawa. In order for 64-bit processors to efficiently use large address spaces while maintaining lower TLB miss rates, the Linux kernel can be configured with base page sizes up to 64 KB. While this benefits access to large memory segments and files, it greatly reduces the number of smaller files that can be resident in memory at one time. The idea proposes a change to the Linux kernel to allow file data to be more efficiently stored in memory when the size of the file, or the data at the end of a file, is significantly smaller than the page size. So, how far is this feature feasible for the linux main line kernel ? Is, this feature already supported ? -- Regards, Sandeep
