Disks: I need to measure disk performance across heterogeneous UNIX boxes, and I'm sick of bonnie++ for a bunch of reasons I won't' waste time on here.
I know from conversations that a few folks here have their own ways of testing disks-
I'd really like to know what people do to measure general disk performance? e.g. really simple tests:
- r/w/d large files
- r/w/d small files
- disk performance when directories contain large numbers of files
I commonly have need to test things like:
- different block sizes
- different inode allocations (UFS/ext3
- different filesystem partition layouts
- different filesystem features (think ZFS fun)
Any thoughts, experiences, urls or shell utils to share?
