We had a similar problem and it ended up being oplocks. It also seemed to manifest itself in office files only, not txt files. Turn oplocks off on one of the qtrees which was having the issue and see if you get the same problem. The command to turn oplocks off is "qtree oplocks qtreename disable" If this fixes the issue I would call support because this should have been fixed in 6.1.1Rx. Later Drew

Hi,

we have F740 and F820 running only CIFS. We hear everywhere that the performance is great of these boxes. We installed the latest 6.1.1R2 (I think) which would solve some problems with virusscanning (trendmicro) on the boxes and clients. When we read a file (doc file) it is somewhat fast, but when we save it it takes twice as long as on a NT box. When we do the same with a RTF file....or TXT it is much faster. Not to say when opening or working with outlook and .pst files on that share, it takes forever.....almost. We see that when we open a file on the box a ~file is created on the same directory too, can this have an influence ? A copy from a file to and from the box....also slow.

We have a 100 Mbit switched network and 1 Gbit links to the filers....other traffic on the network is fast etc. We disabled viruschecking on the filer and the pc's...no difference.

Do we need to tune or set special parameters on the filer ? Somebody has had the same experience....?

Please any info is appreciated.

Geert
