After a lot of time doing some stuff here are the results on the sis controller and a interna supermicro controller I don't know why the internal supermicro controller is so fast. Here are the results: The following results are from testing from the drives connected via port multiplier to the RAID DSA3GPX8-4E controller. Note ada0, ada1, ada2, ada3 and ada4 did not have the SATA2 jumpers, while the rest of the drives did. [root@superstorage ~]# ./read_disk_cache_speed /dev/ada0 65536 10000 10009639 us, 114.472891 MB/s [root@superstorage ~]# ./read_disk_cache_speed /dev/ada1 65536 10000 5713195 us, 114.709895 MB/s [root@superstorage ~]# ./read_disk_cache_speed /dev/ada2 65536 10000 5702896 us, 114.917053 MB/s [root@superstorage ~]# ./read_disk_cache_speed /dev/ada3 65536 10000 5719617 us, 114.581099 MB/s [root@superstorage ~]# ./read_disk_cache_speed /dev/ada4 65536 10000 5720035 us, 114.572726 MB/s [root@superstorage ~]# ./read_disk_cache_speed /dev/ada5 65536 10000 3435868 us, 190.740739 MB/s [root@superstorage ~]# ./read_disk_cache_speed /dev/ada6 65536 10000 3593060 us, 182.396064 MB/s [root@superstorage ~]# ./read_disk_cache_speed /dev/ada7 65536 10000 3490376 us, 187.762006 MB/s [root@superstorage ~]# ./read_disk_cache_speed /dev/ada8 65536 10000 3491744 us, 187.688445 MB/s [root@superstorage ~]# ./read_disk_cache_speed /dev/ada9 65536 10000 3491041 us, 187.726240 MB/s Direct connection from the drive to the card yielded the same results as above. ==================================================================== These results were from the SuperMicro SMC AOC-USAS-S8iR controller. With read cache disabled, the speed is 7.89 MB/s while read cache enabled allows speeds at around 600MB/s root@superstorage ~]# arcconf setcache 1 logicaldrive 1 roff Controllers found: 1 Command completed successfully. [root@superstorage ~]# ./read_disk_cache_speed /dev/aacd1 65536 10000 83328224 us, 7.864802 MB/s [root@superstorage ~]# arcconf setcache 1 logicaldrive 1 ron Controllers found: 1 Command completed successfully. [root@superstorage ~]# ./read_disk_cache_speed /dev/aacd1 65536 10000 1107666 us, 591.658496 MB/s [root@superstorage ~]# ./read_disk_cache_speed /dev/aacd1 65536 10000 1048647 us, 624.957684 MB/s [root@superstorage ~]# ./read_disk_cache_speed /dev/aacd1 65536 10000 1048619 us, 624.974371 MB/s I'm suspecting that the supermicro controller has a bigger cache memory therefore the performance increase. I need to thank Sum my "helper" on getting this testing done for me. Thanks. -- View this message in context: http://freebsd.1045724.n5.nabble.com/Addonics-SIS3124-Controller-and-T-tp4220441p4390480.html Sent from the freebsd-hardware mailing list archive at Nabble.com.
