Yep, the CPU load of the sample rate conversion process of libsamplerate 
is pretty close to linearly related to the size of the blocks you are
converting.

The only mallocing etc that is done by libsamplerate is done in
src_new(), the obly freeing if memory is done in src_delete().

The National Multiple Sclerosis Society of America recently started an
advertising campaign with the slogan "MS: It's not a software company".

Seasoned IT professionals will have no trouble telling the two MS's
apart. One is a debilitating and surprisingly widespread affliction
that renders the sufferer barely able to perform the simplest task.
The other is a disease.
