Are you sure that the mainframe system programmer(s) didn't change anything? Have you asked them about the performance settings of VTAM, TCPIP and the TSM server? Also, like mentioned, make sure your OSA card(s) are set for 100 Full-Duplex. You can see these settings from the HMC or from the OSA/SF utility.
If this is an issue of ALL backup sessions taking longer, then I would look at the performance and settings on the mainframe, not necessarily TSM settings, but OS/390 and OSA settings. I would check with your sysprogs on changes and get them to look at the overall performance of the system while TSM is doing a backup. How do the other server processes run? The backup storagepools... backup DB...? Are they running longer, too? If they are fine, I would concentrate on the OSA cards and/or the VTAM and TCPIP performance settings (Either IPS/ICS for compatibility mode or the service class for Goal mode).

If your client is AIX, run entstat (actually entstat -d ent0) to check your network interface. If there are large error totals, you may have hardware problems.

TSM backup processes that last week took 51 minutes, now take 8 - 28 hours. We know of no changes to the TSM 4.2.1.9 Server running on OS/390 V2R9. It looks like the servers are ready to send data and TSM is ready to receive. The routers are indicate very low activity. We have a sniffer on now. If anyone out there has recovered from a similar experience please help?
