Bigger systems have large buffers.
An hourly cron job to can the sound files you normally use to /dev/null?
Although tmpfs is used extensively in AstLinux, all of the sound
prompts are stored and read from disk. This issue has come up several
times, and I have no idea why they sound so much better in AstLinux.
Don't get me wrong - I'm glad they do, but they should work equally well
for all users of Asterisk, not just those that use AstLinux!
Actually, now that I think about it, AstLinux does have one crucial
difference. By default, DMA for IDE transfers are disabled (better
compatibility with compact flash - rather safe than sorry)... I should
try to enable DMA on a system that supports it and see what happens.
