I'm not sure tmpfs is the right solution for the OP's problem - disk
access slowing down the system. My understanding of tmpfs is that it
will swap pages in and out to/from disk. Wouldn't that be as bad as
directly writing to disk? I can see tmpfs will have some advantage
over direct disk IO when the files are small and short-lived, i.e.
less likely to be swapped.
One way around this is to not have swap at all. Then there is no disk
i/o to worry about. Everything will be in ram.
This is what I do for embedded asterisk servers. tmpfs and no swap.
Ram is cheap.
Problem solved.
I guess it really depends on the load. The OP wants to record 512
concurrent calls. A quick calculation would show that the system will
need (1024 * 8Kb)/second, that's about 8Mb per second. Assuming a mobo
with 12GB of RAM, we're looking at around 25 minutes of calls.
Sounds like a fair deal.
