Windows – Google chrome high hard disk usage

I'm on Windows 7 from boot to VHD. I got a lot of RAM and my pagefile is disabled. This OS can be up for days, even up to 3-4 weeks of working time without restart. I put it to sleep\suspend quite often. I do not know if this is relevant.

I use Google Chrome and I open many windows with many tabs on each window, so it can go up to 100 or more tabs left open for days sometimes. Chrome can consume large amounts of memory for this, so 5 or 8 GB of RAM just for Chrome is usual, but there is still plenty of RAM left free.

The problem is that Chrome is massively using hard drive, even when I do not use it. It can
do it for minutes which makes computer sluggish. Then when I want to open new page it stops sometimes without response, so I need to wait until all disk work is done. From what I figured out read \ writes are mainly to: $Logfile, Jumplisticons, Cache, temp, local storage, so most of it in Chromes User Data directory. Even now I'm just writing this and there is like 30 files that Chrome need to write to and I see constant disk usage.

Is this some kind of bug ? Can I configure it somehow to work as it should ? (I do not want to disable functionality, just to make it work fast)

EDIT:

I figured out some more of this. This read\write operations are mainly in

C:\Users\user\AppData\Local\Google\Chrome\User
Data\Default\JumpListIcons

Chrome just keep creating small files there named like 1ABC.tmp then move them to JumpListIconsOld directory then remove them straight away.
