I leave all CADO processes the default two-threaded unless I run low on memory. But number of threads per process is separate from number of total threads used- CADO defaults to the total number of hyperthreads on a machine, and that is clearly faster than number of cores. In fact, someone 'round these parts said they run 40-threaded on an 18 core HT machine because the overhead threads for DB recording etc are quite slow. Can't say I've tried that extreme myself...

Anyway, if you run 20 threads on a 10-core the specifics don't seem to matter.
