Thanks for your response. We also contacted IBM Tivoli support to get a handle 
on where we should go version wise without having to change everything else.
I quote their reply below:
    "The requirements for TSM for VE is in the link below.  I checked but 
didn't find an apar that matches the performance issue of maintenance plan and 
reclamation running slow.  I would suggest that you upgrade to 6.3.2.0 on the 
TSM server code so that you can use TSM for VE and that seems to be a pretty 
stable version. 

For 6.2, 6.3 and 6.4 requirements for  TSM for VE: 
http://www-01.ibm.com/support/docview.wss?uid=swg21505139 "
The main reason we are considering updating is that our Maintenance plan is 
running extremely slowly, and we were under the impression that it was a known 
issue, and fixed in a later release. That seems to not be the case, though.
Any insight would be greatly appreciated,

Thanks again,
Marc

Hi Marc,

Your Administration Center at same or higher level than your TSM Server. 
Current highest versions for both is 6.3.4.

Objet: [ADSM-L] Updating TSM Server to 6.4, Will Storage Manager Administration 
Center (6.2.1.0) Still work?

We are currently running TSMPROD1_SERVER1<http://10.42.196.138:1581>, platform: 
Windows, version: 6.2.1.0, and using the Storage Manager Administration Center 
6.2.0.
We plan to upgrade our TSM server to 6.4. Will we still be able to use the TIP 
to access the server?
