Yeah, I had the same issue when I did the AIX system update to TL 7 SP4 last year. All the recommendations from that article have been implemented, but there's still about a 50% reduction in backup db throughput since the TSM update. Maybe TL 7 SP6 interacts with the loopback device differently than SP4 does?

I followed it and it fixed the slow backups. http://www-01.ibm.com/support/docview.wss?uid=swg21587513 Pam Pam Pagnotta AHE Tivoli Storage Manager Administrator/AHE Storage Administrator/ AHE z890 Administrator Criterion Systems, Inc Contractor to U.S. Department of Energy Data Center & System Services Group 301 903-5508 - Office ============================================================================================= Date: Tue, 22 Apr 2014 09:18:10 -0600 From: Matthew McGeary <[email protected]< mailto:[email protected]>> Subject: Re: TSM 7.1 install on AIX problems I just did the install last week and didn't see any issues with the install script or memory dumps. What version of AIX are you running? I'm on 6.1 TL 7 SP 6 (I updated from TL 7 SP 4 in order to do the TSM 7.1 install.) I am seeing abysmal speeds during backup db commands (about half the average speed I was getting before,) but that's neither here nor there. Sigh.
