(as before, this is under VMWare 2.0.5, latest plan 9 ISO) time goes much faster than it should, and the VM hangs up for approx 7 seconds every 40 seconds or so. after a hangup, system time proceeds even faster for a little while, before settling down again. i've attached a pdf graph of the behaviour (times in seconds, real time on the x-axis, system time on the y-axis, data points generated by looping alternating reading /dev/time and sleep(1000)). the blank spots in the graph are where the system was hung up unresponsive, not even the mouse cursor moves. anyone got any idea what might be going on here?

This system has been behaving perfectly on every installation (save where i really botched something up trying to learn the system). What is your host OS? I'm running this on Mac OS X 10.5.8 hope we can get you a fix for this soon, respectfully, ++james ^ permalink raw reply [flat|nested] 9+ messages in thread
