Because in\nthis case a page can have multiple buffers and even if a page is not\nuptodate, some buffers can be uptodate.\n\nSo I suggest that when all buffers which correspond to a part of a file\nthat we want to read are uptodate, use this pagecache and copy data from\nthis pagecache to user buffer even if a page is not uptodate. This can\nreduce read IO and improve system throughput.\n\nI wrote a benchmark program and got result number with this program.\n\nThis benchmark do:\n\n 1: mount and open a test file.\n\n 2: create a 512MB file.\n\n 3: close a file and umount.\n\n 4: mount and again open a test file.\n\n 5: pwrite randomly 300000 times on a test file. offset is aligned\n by IO size(1024bytes).\n\n 6: measure time of preading randomly 100000 times on a test file.\n\nThe result was:\n\t2.6.26\n 330 sec\n\n\t2.6.26-patched\n 226 sec\n\nArch:i386\nFilesystem:ext3\nBlocksize:1024 bytes\nMemory: 1GB\n\nOn ext3/4, a file is written through buffer/block.
