This is a new thread, but here goes..... Has anyone noticed strange performance problems under 10.2? I have noticed that things which were once fast now use inordinate amounts of system time. For instance, setiathome (the unix command line version) uses almost 25% system time, whereas before it used only a few percent system time. Monitoring it with "top -es 3" shows that it is performing almost 1,000 context switches per second. For instance, here's the setiathome line from my top output.... 3757 setiathome 49.9% 36:17:02 21150597 3129 34 306551 306542 38928334 306576 30614876 Thirty million context switches, and 38 million syscalls. I'm pretty sure this didn't happen before, and it certainly didn't use 20% or more system time. I've also noticed that setiathome noticeably slows my computer while it is running alongside some other relatively intensive programs, whereas it didn't do so before. Furthermore, it seems that the whole system is just less responsive when one program starts misbehaving (this is very subjective, I know) possibly because too much time is being spent in the kernel, thus preventing really fine grained multitasking. Does anyone know what's up with this? I don't think I'm imagining this, what has changed?
