Re: [Zim-wiki] profiling zim for performance?

[Stephen LARROQUE]

Ah then there are also cpu profilers. Have a look at my project:

https://github.com/lrq3000/python-easy-profile

If you run this against Zim from source, it should profile both cpu and
memory (depending on the switches you use).

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.

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
7a373a788194c36723bd0eed600291e513de9396).

I have not enabled any plugins besides the tray icon.

This is most likely a memory sink issue if it becomes more sluggish over
time. Valgrind can be used to profile memory and garbage collection, or
since zim is a python program you can also use the memory_profiler module.

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?

[Zim-wiki] profiling zim for performance?

[Nathaniel Beaver]

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 
7a373a788194c36723bd0eed600291e513de9396).


I have not enabled any plugins besides the tray icon.
