Slow IO on SSD disk
Hi all, I've a Lenovo T400 laptop with a SanDisk 64GB SSD disk. It used to have Debian 7 on it (everything working just fine), and now I want to use it as my personal laptop with OpenBSD. I've installed 5.4. Everything is working great (sound, webcam, etc) but disk. I get ~40MB/s writing and reding to and from disk. This very same disk reported 250MB/s reading and 190MB/s writing on debian7. I somehow expected some decrease on those numbers (which I don't care), but the performance that it's giving is more like an IDE disk ... I've tried with softdep and noatime with no success. Any ideas ? Thank you. dmesg: OpenBSD 5.4 (GENERIC.MP) #41: Tue Jul 30 15:30:02 MDT 2013 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 4204466176 (4009MB) avail mem = 4084817920 (3895MB) mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.4 @ 0xe0010 (80 entries) bios0: vendor LENOVO version 7UET82WW (3.12 ) date 01/13/2010 bios0: LENOVO 2768HH4 acpi0 at bios0: rev 2 acpi0: sleep states S0 S3 S4 S5 acpi0: tables DSDT FACP SSDT ECDT APIC MCFG HPET SLIC BOOT ASF!

Reading *from* said device is not a problem though. Just don't get it the wrong way... :-) Cheers,

I get ~220MB/s reading and ~170MB/s writing using the same exact disk on an x200 running -current. If interested, I will get to post a dmesg later when I have access to the machine. I used dd as well with if=/dev/zero and bs=1M. Hi, just upgraded to -current. After that with no ther modifications I get ~190MB/s reading and 110MB/s writing, which is ok for me. dmesg is attached just in case is useful.
