Linux and Solaris performance
We have an interesting quandry here. When I'm rsync'ing my directory
tree (100 directories each containing 1000 files) I see some strange
results:
All of these machines are on their own network segment (100t) in our QA
lab
Solaris->Solaris - time taken: 11m32s
Solaris->RH Linux 7.2 - time taken: 206s
RH Linux->Rn Linux - time taken 1m59s
In each instance I have rsync running as a server on the target machine
(Linux in each case). I just can't explain why the performance is just
so AMAZING on Linux. Any ideas?
Thanks
Dave

ZFS speed degraded in S10U4 ?
...system on dedicated disk, and I''m working with same files which are on same physical cylinders, so it''s not likely a problem with HDD itself.
I''m doing as simple as just $time dd if=file.dbf of=/dev/null in few parallel tasks. On Update3 it''s somewhere close to 11m32s and on Update 4 it''s around 12m6s. And it''s both reading from compressed or uncompressed ZFS, numbers a little bit higher with compressed, couple of seconds more, which impressive by itself, but difference is the same, and strangest part is that reading file from compressed ZFS on...
