I am running build SXCR 39 on my Sun Blade 100 and the performance on it is horrible lately. How horrible you ask? JDS is almost unsable because the mouse is jumpy and typing lags. The uptime load average is over 4 at idle for JDS. But how about this as a benchmark for building build 40:
==== Total build time ==== real 44:57:10 The longest this has taken a few builds back was around 10 hours. Nothing else of any significance was running when I did the build. I did notice using top that during the build the CPU was at 100%, as to be expexted, most of the CPU was being used by the kernel, usually over 60% and around 30% for user processes and load was pretty much over 6 the whole time. One difference I have with build 39 on this box is that I am running ZFS for my home directory (compression is turned off). Could ZFS cause that much overhead? I am doubtful so I don't want to go fdisking my machine just yet. I would appreciate any suggestions for troubleshooting the issue. With DTrace it should be easy to discover the problem but I need some advice on where (and maybe in how) to start.
