Hello,
I wonder our network or netapp filer seems to have very low perfomance.
For some software publisher I was asked if I could try some tar operation to check our system.
However the operation took about 8min while using netapp filer. However when I do same operation on local /tmp the operatien takes 10s.
Number of files in workarea=4000 and size is 390MB,
cd /path/to/workarea cd ..
time tar cf workarea.tar ./<workareadir>
3.232u 13.710s 7:47.04 3.6% 0+0k 302304+772848io 0pf+0w du -hsc workarea.tar <workareadir>
379M workarea.tar mkdir nfs_test
mv workarea.tar nfs_test
time tar xf workarea.tar

mkdir -p /tmp/localdisk_test
cd /tmp/localdisk_test
time /bin/cp workarea.tar /tmp/localdisk_test

time tar xf workarea.tar
1.224u 10.427s 0:12.21 95.3% 0+0k 64+302304io 0pf+0w
time tar cf workarea2.tar ./<workareadir>
0.488u 2.238s 0:02.73 99.2% 0+0k 40+1546312io 0pf+0w
I wonder if our filer is set up properly. Maybe do you have an idea if those differences are reasonalbe.
The netapp filer was bought about 3y ago.
Best regards,
Ingo
