[MHo] 2017-07-31 There's something that I don't understand: Why ist the runtime of ====== set pool1 [tpool::create -minworkers 10 -maxworkers 20 -idletime 10 -initcmd $initCmd -exitcmd $exitCmd] ====== double the time of ====== set pool1 [tpool::create -minworkers 20 -maxworkers 20 -idletime 10 -initcmd $initCmd -exitcmd $exitCmd] ====== (The workers are only sleeping using after 10000 in this case.) The first call runs ~20,xs, the second one, as expected, ~10,xs. The documentation states, the only difference is the time at which the workers are created - beforehand, or "on demand" when a post is done. As there enough -maxworkers defined, what is limiting the operation then...?
