Howdy! I inherited care & feeding of a Quantum Superloader3-DLT-V4 library 
driven by NetWorker. I didn't look too closely at it for 6 months because it 
met needs and was working fine. Lately it's developed a couple quirks and I've 
been digging into it in more depth. It's got an issue I'm working on where it 
becomes unresponsive after sitting idle between jobs for a while, but this post 
is for another reason:

While operating (apparently) normally, it never exceeds 1800KB/Sec throughput, 
which calculations based on the documentation says is only about 20% of 
expectations. I've reviewed the settings, and everything appears to be correct. 
I've added additional network bandwidth, and confirmed that the processor / 
drive / memory requirements appear to be optimal... I'd appreciate any 
suggestions on a course of diagnosis and correction, since it would improve 
efficiency & reliability if jobs completed as quickly as possible.

ANY help will be greatly appreciated. I'm presently studying all the 
documentation in depth hoping for insight.

Thanks in advance to anyone who has advice on this (or my 
idleness-responsiveness) issue!
