Optimizing decoding performance

[bjornekelund]

The config file suggests using wave files is faster than shared memory. It seems somewhat counter-intuitive but I tried it anyway, using a RAM disk as D:\ and setting transfermethod=wavefile. CWSL_DIGI still reports the shared memories when starting up and I see no noticeable change in CPU load. Is there something I have missed? I decode thirtysomething FT4 and FT8 segments.

Doing more tests I can actually see the CPU load increase slightly when using the wavefile transfer method. Could this perhaps be because I use a RAM disk? Also, intuitively, shared memory should be lighter on CPU.
