Re: Low perfomance when read from usb flash drive
Hi please explain what kind of test you have done. It's most likely not related to USB, but rather the file system. Maybe you can run the following test on Windows and FreeBSD to compare: dd if=/dev/da0 of=/dev/null bs=65536 I'm test on FreeBSD7-stable and FreeBSD-current and post results. Flash drive, FS, computer the same. Windows only for example. PS dd makes the same result - problem not in the file system dd if=/dev/da0 of=/dev/null bs=65536 7281+0 records in 7281+0 records out 477167616 bytes transferred in 36.602952 secs (13036315 bytes/sec) systat -vm Disks ad4 ad6 da0 cd0 pass0 sg0 sg1151844 wire KB/t 27.33 0.00 64.00 0.00 0.00 0.00 0.00198628 act tps 9 0 200 0 0 0 0758680 inact MB/s 0.25 0.00 12.50 0.00 0.00 0.00 0.00 1660 cache %busy 0 099 0 0 0 0288948 free -- С уважением, Артём Миргородский tel: (056) 373 42 84 Jabber Id: artyom.mirgorod...@gmail.com mailto: m...@alkar.net ___ freebsd-usb@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to freebsd-usb-unsubscr...@freebsd.org

This is exactly opposite of the results that I'd typically see through the filesystem (ufs). For usb1 I'd see about 15MB/s and for usb2 I'd see between 16MB/s and 18MB/s. Since this is all ufs, no windows numbers are available for comparison. These are the numbers reported by gstat, so it includes all the filesystem traffic. So a drop from 20MB/s to 12MB/s would be somewhat out of my range of experience...
