IOzone for filesystem performance benchmarking

Thu, 03 Jul 2008 08:00:00 GMT
IOzone lets you benchmark your filesystem performance, seeing how well record IO occurs for files of various sizes. With IOzone you can see more detailed information than the read, write, and rewrite figures that Bonnie++ reports. IOzone is great at detecting areas where file IO might not be performing as well as expected.

bup-drecurse(1) 					      General Commands Manual						   bup-drecurse(1)

NAME
bup-drecurse - recursively list files in your filesystem SYNOPSIS
bup drecurse [-x] [-q] [--exclude path] [--exclude-from filename] [--profile] <path> DESCRIPTION
bup drecurse traverses files in the filesystem in a way similar to find(1). In most cases, you should use find(1) instead. This program is useful mainly for testing the file traversal algorithm used in bup-index(1). Note that filenames are returned in reverse alphabetical order, as in bup-index(1). This is important because you can't generate the hash of a parent directory until you have generated the hashes of all its children. When listing files in reverse order, the parent directory will come after its children, making this easy. OPTIONS
-x, --xdev, --one-file-system don't cross filesystem boundaries. -q, --quiet don't print filenames as they are encountered. Useful when testing performance of the traversal algorithms. --exclude=path a path to exclude from the backup (can be used more than once) --exclude-from=filename a file that contains exclude paths (can be used more than once) --profile print profiling information upon completion. Useful when testing performance of the traversal algorithms. EXAMPLE
