Paul's experience is more consistent with what we're observing as well. Following conversations with TSM support, I don't have a lot of hope for improvement - getting answers like "have you considered moving the server to z/OS?" after telling them that the system has only IFLs available tends to tell me they don't really want to support this platform...8-(
These are going to two TS1120 tapes connected via Fibre Channel to their own little Ficon port on the zSeries machine. On an IFL, just doing a simple 'dsmc archive "/cti/*"' for say, the 80 gigabytes of images, will easily soak up 200 mips, and take over 20 hours. You don't wat me to tell you how long a selective backup takes... Obivouisly, either something is drastically wrong in the the zLinux, the tape drivers, or most likely, that pesky database is too damn slow.
