OK, I've put a load more options in /etc/system on the sun as suggested by andrew bond and others. The network checks out, everything 100mb-FD still only get around 1.5mb/s for sequential reads. While doing this filer is: 21% 261 9 0 715 1111 1014 850 0 0 7 24% 258 9 0 707 1223 1252 881 0 0 7 28% 333 8 0 708 1765 1649 861 0 0 2 25% 298 8 0 689 1483 1330 670 0 0 2 28% 296 8 0 818 1355 1822 1019 0 0 2
Interestingly if I do large numbers of random reads (32 streams of 8k random reads) I can max the filer out, around 6mb/s disk reads and 97% cpu usage. This looks to me like the network is ok but something subtly odd is going on somewhere. any smart ideas?
