hello, a puzzle i hope you can shed some light on: I have two systems, built at different times, but running very similar software configurations (same hardware, patch rev). They *should* have near-identical load, as they are performing the same function in parallel behind a load balancer.
However: system#2 is noticeably and consistently slower than system#1 (both are under high load): # sar -p 2 5 SunOS *system#1* 5.10 Generic_125100-10 sun4u 09/26/2007 14:47:32 atch/s pgin/s ppgin/s pflt/s vflt/s slock/s 14:47:34 28.77 0.00 0.00 3439.18 196.59 0.00 14:47:36 23.69 0.00 0.00 2989.68 289.74 0.00 14:47:38 25.76 0.00 0.00 3312.57 270.75 0.00 14:47:40 17.61 0.00 0.00 1456.07 230.99 0.00 14:47:42 16.02 0.00 0.00 1474.72 140.62 0.00 Average 22.37 0.00 0.00 2534.78 225.69 0.00 # sar -p 2 5 SunOS *system#2* 5.10 Generic_125100-10 sun4u 09/26/2007 14:45:51 atch/s pgin/s ppgin/s pflt/s vflt/s slock/s 14:45:53 371.08 0.00 0.00 19009.31 1405.88 0.00 14:45:55 55.12 0.00 0.00 124.88 454.63 0.00 14:45:57 381.28 0.00 0.00 15695.57 993.60 0.00 14:45:59 149.51 0.00 0.00 19591.18 1829.90 0.00 14:46:01 125.00 0.00 0.00 12613.73 1639.71 0.00 Average 216.08 0.00 0.00 13391.67 1264.22 0.00 system #2 has a zfspool and a few (zfs) filesystems, which system#1 doesn't have. Otherwise, I'm unsure of what might be causing this. Thoughts on what I should be looking at? much thanks, Jonathan. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
