Comment # 28 on bug 1014999 from Episteme PROMENEUR

Compaq presario CQ61, 4 Gb
Dual boot window 7 and leap 15
sanpper disabled, zypper snapper plugin not installed

since update from 42.3 to leap 15

random gui slow down or freeze

during freeze there are many many disk accesses.

phenomenon occurs  till 1 to 10 mn

phenomenon occurs whenusing an app
can occur with Firefox, kmail, digikam. i use them frequently.

i assume this : 
 swap problem
- swap "0 M used" => no problem
- swap "400 M used" => problem
or

baloo problem

or 

something else
