Hi,

We upgraded one of our servers to 3.1.0.2 around 3 weeks back. For a
while there, things were going pretty well. We now have a severe
performance issue. Some restore and retrieve operations that used to
take seconds or a small number of minutes, are now taking a large number
of minutes. For example, a retrieve of 7.2 GB that used to take 34
minutes, this morning took after 2.5 hours. Once the data transfer is
happening, it goes well. The part that is slow is selecting the files to
retrieve. Using the GUI, trying to expand each level of the directory
structure can take up to 30 minutes.

The clients are a mixture of WindowsNT, Digital Unix and VMS. With the
exception of VMS, the clients are running ADSM 3.1. The filespaces
involved are on the large size (hundreds of thousands of files).

We had this problem last week, and a restart of the ADSM server improved
things markedly. Today that doesn't help. As was discussed here a week
or so back, the cache hit % is critical. We were running at 96% or
thereabouts, so I increased the cache from 16MB to 32MB. This doesn't
appear to have helped at all either.

Any suggestions?


Thanks,

Trevor
