You can configure the minimum, average and maximum chunk size that should be generated by
casync.
I played a bit around with casync (but with the default settings). Here are my results:
During generation of index files and chunk stores, casync utilizes 1 CPU core @ 100%, but
it does almost need no RAM. Tests were made on a Intel(R) Core(TM) i7-6700HQ CPU @
2.60GHz.
