asterisk users - Apr 2010 - Cache sound files for faster processing

Dear List,

Are there any way of configuring of Asterisk so it'll cache sound files in
memory, and when Asterisk receive a call, instead of loading sound files from
the disk, it will load from the memory and so Asterisk can process much more
call at a time than with faster speed it is not caching.

Thanks,

Not directly, but it's not really needed. A long as the machine has
enough RAM, the files will be served from RAM by the operating system.
Sure there is the overhead of opening/closing files and reading them,
but on modern OS this overhead is negligible if the files are cached
(asterisk may even use mmap, but I'm not sure).

You can also make a ram disk (say via tmpfs), copy the sounds there
and symlink the sound directory to that location. However, I don't
think you will gain much.

Aside from the suggestions, you could try out an SSD drive, which is
both expensive compared to a traditional hard drive and very fast.
