* Linux performs random seeks twice as fast as Solaris ufs for large files, and
more than four times as fast for small files.
* The behavior of Solaris tmpfs is
similar to Linux ext2. Although character input and output
is faster on tmpfs, block input and
random seeks on the two are the same. Block output is faster on tmpfs, though the
difference becomes smaller as file size is increased.
* For block input and output, the two
are roughly the same for large files (>100 MB), but for
small files, block output on Linux
is 6 times as fast as Solaris.
* Solaris ufs outperforms Linux ext2 on character input and output
This was with Bonnie to test, using Solaris 7 and Linux 2.2 - I didn't know
ext2 kciked bog standard ufs's ass that much. There were (and more are due in
the upcoming update releases) improvements in UFS performance in Solaris 8
These results were without write-caching.
