I would guess that you have a hyperactive clipboarrd manager that
repeatedly asks Gnumeric for the current selection in all the possible
formats that Gnumeric offers.
Try running with GNM_DEBUG=clipboard set. If you see a flood of
messages, that is the cause.

Hello,
I'm having issues with Gnumeric (v1.12.9) being unusably slow on my Athon X2 2 GHz dual core, Linux Mint
17.1.
It starts out OK, but as I'm editing the spreadsheet, I have to wait 0.5 to 1 seconds for every click,
paste, tab switch, etc. Also switching to the application is slow by the same amount. It gets worse the
longer I work on the spreadsheet. However, it seems to correct itself when I go to the preferences and
click close again (but I do want to confirm this better, though).
Attached are some valgrind/callgrind analyses. First I ran 'callgrind_command -z', edited a column and did
'callgrind_command --dump'. I did the same after having used the spreadsheet for a while. Screenshots of
the analysis using KCachegrind are also attached.
It's hard to say anything conclusive from this, but it stands out that gobject::g_type_check_instance_is_a
is called a whole lot more (from 680,000 to 2,100,000). What also stands out to me is that mutex locking
and unlocking, a slow process in and off itself, has increased 5-fold. (I also wonder what needs to be
locked 166,000 times to begin with...)
At first I thought my laptop with Intel i7 (also having Linux Mint 17.1) didn't have this, but it's just
too fast to be immediatly noticable, it seems. Valgrind shows the same results.
I was hoping for some insight.
