There can never be a reasonable number quoted. It all depends upon the number of threads that your build job uses, how disk-bound or network-bound each job is, how overloaded the VM host machine is, how much spare RAM is available, etc.
I myself have a large number of C++ jobs using gmake –j, so all processors are inherently utilized on the slave machine. Consequently, I always limit the number of executors to one.
