Re: [Discuss-gnuradio] GNURadio File meta Sink performance.

[N. Benes]

If you are on Linux you could just create a file in tmpfs (i.e. RAM).
Use a File Sink with a file in "/dev/shm" for instance (see "man mount"
to configure tmpfs).
Of course you then probably need a lot of RAM (or can capture only small
durations). But it is much faster than disk I/O...
