Steven Pratt aed75ff3ca [PATCH] readahead: fix initial window size calculation ... The current current get_init_ra_size is not optimal across different IO sizes and max_readahead values. Here is a quick summary of sizes computed under current design and under the attached patch. All of these assume 1st IO at offset 0, or 1st detected sequential IO. 32k max, 4k request old new ----------------- 8k 8k 16k 16k 32k 32k 128k max, 4k request old new ----------------- 32k 16k 64k 32k 128k 64k 128k 128k 128k max, 32k request old new ----------------- 32k 64k <----- 64k 128k 128k 128k 512k max, 4k request old new ----------------- 4k 32k <---- 16k 64k 64k 128k 128k 256k 512k 512k Cc: Oleg Nesterov <oleg@tv-sign.ru> Cc: Steven Pratt <slpratt@austin.ibm.com> Cc: Ram Pai <linuxram@us.ibm.com> Cc: Trond Myklebust <trond.myklebust@fys.uio.no> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>		2006-03-22 07:54:03 -08:00
