    Lots of tuning possible but every environment is different and what helps for one site may hinder another!

    The ch value is the maximum cache value - everything explained here : http://www.symantec.com/docs/HOWTO34665

    Running backups and duplications at the same time is not ever going to be great - which i assume is why in 7.6 SLPs get a schedule window and others use a scheduler to suspend and enable them so that they don't run while backups are running.

    Queue processing, garbage collection and rebasing can all also have an affect and this is another juggling act - again people are adding the extra queue processing runs to the crontab to keep it running lean

    The readme for 2.5.3 is interesting ...

    Better battery backup monitoring, catalog busy error fixes, well .. when you read all of the content through it does make you feel like you have to have it!

    I guess now that 2.5.3 is here that Support / Symantec will say try that first?

So not sure if this means it is working, but that is the output that is scrolling by.
