KMM 4.7.2 atrociously slow - unworkable

[Louis-Philippe Allard]

Hello maillist,

since I migrated to 4.7.2 from 4.6.2, KMM became extremely slow, to  
the point of not being able to produce any significant work.  Every  
click of the mouse takes between 5 & 10 seconds no matter what I am  
loading (contextual popup, or loading a ledger, or payees, etc).  This  
is noticeably slower when in the Accounts page but overall, its slow  
to the point that it becomes frustrating to use it.

I eliminated database problems with a replication to another DB, then  
using 4.6.2 on this replicated DB, it is much much faster and snappier  
(when I do something something happens).

I noticed KMM 4.7.2 is fast for a few minutes when I start it back up,  
but after that delay, it becomes hellish.

CPU and RAM are comfortably low (<10% CPU, RAM < 1.5GB) but  
nevertheless, I noticed CPU is always between 7-10% unless I do  
nothing at all (let it alone).

Is there a debug mode or something I could do to pinpoint the source  
of this extreme lack of performance?  Has anybody else noticed 4.7.2  
being notoriously slower than previous releases?

Searching the KDE bugs, bug 360874 seems to be similar or somewhat  
related to what I am experiencing, except that I am running on Linux  
Mint 17.3.  Workstation has quad core AMD Phenom II X4 965 at 3.4GHz,  
and 12GB DDR3-1600 RAM.

Thanks
