Howdy, just installed latest zeromq from git (2.1.7) on OS X 10.6.7. This is a 2011 MBP with lots of free RAM and an SSD. Running into few problems that don't seem to show up in irc or mailing list logs...
Second… using the taskvent, taskwork2, tasksink2 example code has very odd performance behavior… regardless of the number of workers, it will zip along to ~80% done and then the performance drops down a lot. On successive runs, the performance degrades even more.
E.g., for 5 workers, instead of the expected ~5 seconds it ends up taking longer and longer on each run. 12 seconds, 30 seconds, the last run was 110 seconds. That's a bit disconcerting. :-) :-(
