Try moving your TCPBUFFSIZE to 512 instead of 32.

I made the tcpip performance changes to the dsm.opt and I am still getting
slow transfer times.  I tested via ftp and was able to tranfer 40,000 files
in a few minutes.  So it appears that the TSM client is still not working.

here are the stats from my last selective backup:

Total number of objects inspected:      600

Total number of objects backed up:      600

Total number of objects updated:          0

Total number of objects rebound:          0

Total number of objects deleted:          0

Total number of objects expired:          0

Total number of objects failed:           0

Total number of bytes transferred:   230.73 KB

Data transfer time:                    0.00 sec

Network data transfer rate:            0.00 KB/sec

Aggregate data transfer rate:          0.21 KB/sec

Objects compressed by:                    0%

Elapsed processing time:           00:18:06


here is the new improved dsm.opt
