I run several machines with Ubuntu Desktop and always update them to the next version (albeit gradually, one after another). after upgrading 5 of my machines to 14.04 I noticed a significant slow down in disk ops. Or maybe it is just more of them. For instance, starting a chromium browser, or a firefox now takes 30-40 seconds of disk thrashing with IO, mostly reads. This was not so in 13.10
I first noticed this on a slow Intel I3 3GB laptop with HDD. This is my only 32 bit machine, at that point I thought this is because 32 bit, outdated, and the machine itself is slow. did not pay much attention. But then I upgraded my Intel I7 8GB laptop (also HDD) and noticed the same increase in disk IO.
after that I upgraded my desktops (all have a minimum of 16 and up to 32 GB RAM, top intel I7) and noticed the same thing except for the 2 machines that had SSD.
Ok, SSD does not slow down, I get this, but why was 13.10 like 5 times faster on all my HDD machines?
I have not yet upgraded to 14.10, maybe I skip this for 15.04
does anybody notice the same thing?
