Reboot Cures Stuttering?

[PeteCress]

I'm back to struggling with the stuttering thing. Playback keeps stopping momentarily, and then resuming.

Been to the Java memory allocation and maxed it. Setup | System Information | JVM Heap Size (Used/Total/Max): 173MB/319MB/1038MB seems to confirm.

The only reliable cure I have found is a re-boot.

Anybody been here? If so, what did you find?

In case somebody else is having the same problem...

It seems like in my case it was not the Java Heap Size thing.

Instead, it was the blocking on my RecordedTV drives.

My NAS box had been getting a little too full, so I moved RecordedTV to a couple of local drives on the Sage box.

When I did it, I forgot about the admonition to set blocking to 64k and would up with the default 4k blocks.

Re-blocking the drives *seems* to have cured both the stuttering/pausing and some intermittent heavy pixellation that I was trying to ascribe to signal strength.

Not knowing that much about the nuts and bolts, all I can think of is that, as the discs inevitably became heavily-fragmented, the time spent chasing down all those 4k blocks (vs only 1/16th the time for 64k blocks) was causing the problems.
