NetApp Filer

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

5.611u 64.788s 17:32.43 6.6% 0+0k 772784+302304io 0pf+0w

mkdir -p /tmp/localdisk_test

cd /tmp/localdisk_test

time /bin/cp workarea.tar /tmp/localdisk_test

0.000u 0.427s 0:00.43 97.6% 0+0k 0+772784io 0pf+0w

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
