So I'm guessing either you had the problem and figured, "let's upgrade, see if that fixes it" (not a bad plan), or you are a regular upgrader (also good). Can you say if the problem started with an upgrade? Or did it occur between upgrades? Hm, well, yes, I am upgrading regularly. It's my home system, so nothing mission critical. And therefore why not upgrade it and see what new you guys are cooking ;-) Usually upgrading on weekly basis. ... sd0 at scsibus1 targ 0 lun 0: Any possibility you have a bad disk? No, it seems more like it is software problem. I did some tests, and came to a conclusion that it is chromium, some how while it is not in top for cpu it slows down things significantly. for now switched to firefox and problem disappeared. But, just for the record, firefox had issues with sigbus/segfault around a week ago. Now it is rock solid and fast again.

A few times in my life, I have seen a bad disk that would have issues reading from the drive, but succeed after a few retries, before it threw an error back to the OS. It would then reset its retry counter, and have the same problem on the next read...and the one after that. Result: horrible performance, but it "worked". (granted, I've been doing computer support for almost 40 years now and I can think of two cases of this happening that left me scratching my head for a long time, and maybe a couple others similar to this that I don't recall so vividly, so not exactly a common problem...but not unheard of, either.) ...

system slow down strangeness
Hello, from around two weeks ago I am observing the overall system slow down. Everything work stable, but nearly every X application takes forever to open a window. also I am using tiling wm, and when workspace is switched, it takes a long time for the system to redraw a screen. I also noticed that some console scripts like ansible-doc are also starting slower then usual. this system only has 8 Gb RAM temporarily, but top says: Memory: Real: 1764M/5673M act/tot Free: 2183M Cache: 3284M Swap: 0K/32G so I do not think it is a memory issue. was just fine before, so wondering what has happen.
