Re: profiling zim for performance?

Thanks for the suggestion, but it's the CPU that spikes when I change
pages, not the memory.
But note that i never experienced such an issue (but i leave zim open
max for 1d,then i don't fear closing since it memorizes cursor position
and documents history). Maybe it's the fault of a plugin?
I suppose it's possible that the tray icon plugin is responsible, but I
don't think it's likely.

When I first launch Zim, it is quite snappy. However, after it's been
running a while, opening even the smallest pages becomes sluggish.
What would be a good method of profiling Zim's performance to help
understand this behavior?
I've tried using `strace', but it just shows Zim is polling a lot, and
I'm not sure how to interpret the results.
I am using Zim 0.65-4 on Debian Stretch and have also verified the same
slowdown on the latest Github version (0.67, SHA1 is
I have not enabled any plugins besides the tray icon.
