Abnormal disk I/O on new laptop

G

G_Nerc

Good day!
I have a some problems with my new laptop:

Laptop info:
  • Processor: Core i5 3210M 2500Mhz
  • CPU Cores: 2 (4 virtual HyperThreading core)
  • RAM: 4Gb
  • Video: NVIDIA GeForce GT 630M 1Gb VRAM
  • HDD: 500Gb SATA AHCI
dmesg on pastebin.com
First of all I'm setup on that laptop FreeBSD 9.0 amd64 memstick. Without any port installing and system tuning (only add user and set root password). After that I see that when I'm run # portsnap fetch extract it start extract ports after fetching it is very slow (after 20 minutes it extract only games section) and I can't wait for it ends.

After that I'm csup to HEAD and buildworld and kernel (kernel - GENERIC without all debug - options like WITNESS,DEBUG, DTRACE,DDB etc.) I'm do all step by step from /usr/src/Makefile but after that problem not solved.

Also I notice that moment:
If I start diskinfo -t ada0 after system starts, all ok with I/O. Disk speed is fine and no problem. When I start portsnap extract first category (audio) extracts fine and fast, after that all speeds down and gstat shows that disk 100% busy. If I stop portsnap extract and start diskinfo -t at once it show speed about 8Mb/s. But when I restart that test after several minutes it shows speed fine about 100MB/s.
Seems like many small files from portsnap extract fill disk queue or something like this.

/var/log/messages have not any errors, and console output have not it too.

I'm install on that laptop windows 7 and it has not that problems.

Below output various data when portsnap extract run.

I'm find solution and problem:
I'm disable
Code: 
device ses
in kernel config and rebuild it.
I think it relates to Intel Management Engine Interface, and there is line for that device from dmesg:
With [device ses] in kernel config
Code: 
ses0 at ahciem0 bus 0 scbus3 target 0 lun 0
ses0: <AHCI SGPIO Enclosure 1.00 0001> SEMB S-E-S 2.00 device
ses0: SEMB SES Device

Maybe that helps to someone else!
 
Sorry, but I have some doubts about correctness of your guess. I can't imagine relations between SES driver and disk performance. What is quite realistic is that write of many small files by portsnap show heads seek bottleneck of the HDD.

Click to expand...
But I had system performance problems not only with portsnap, it appears when I delete /usr/obj, when I'm do csup, and when I disable device ses in kernel config, all disk problems ends.
I don't know possible that or not, but about a week I have problems, when active disk I/O freeze my system to 10-20 sec, and after that procedure that does not appears.
If it needed, I can do some tests which you say, for isolating that problem.
