With my Soekris net5501, without the driver I've got around 3MB/s with sftp and around 5MB/s with the driver. On 7.X you need to patch openssl to make it use the crypto framework by default, don't know for 6.X > However, this doesn't seem to be related to geli. The cpu is pretty > much idling: I tested with geli (on an usb drive) and I didn't notice any improvement too. I think that the crypto stuff is not the limiting factor but the drive's speed. Anyway the driver should save some load on the CPU. > last pid: 2769; load averages: 0.06, 0.10, 0.08 up 0+00:18:04 > 12:23:07 39 processes: 1 running, 38 sleeping > CPU: 0.8% user, 0.0% nice, 16.7% system, 9.3% interrupt, 73.2% idle > Mem: 25M Active, 100M Inact, 35M Wired, 6192K Cache, 27M Buf, 588K > Free You can see the driver's CPU usage with top S H (the glxsb0 taskq entry) > Anyways, thank you for your work on backporting the driver, > Patrick! :) Enjoy :) Regards. _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
