Sometimes, when I open a note, the QON doesn't respond about 3-6 seconds.

Thank you for reporting, I can't reproduce that on any of my systems.
Can you please post the output from the debug settings (see issue template).
And is there any useful log output if you enable the log panel (see Window / Panels)? Please make sure you also enable debug logging.

@Waqar144, I can't see any spellchecking. Can that still be a thing?

[pbek]

@ivanpirog and can you please upload an example note file that takes long to load.

@ivanpirog

• did you build yourself or using pre-built binary?
• Can you tell us about the file size of the note which takes long to load?
• Can you confirm whether spell checking is enabled or disabled in Main menu- Edit -> Check spelling?
• Can you tell us which version of QON you are using?

@pbek
Spellchecker can be enabled but if there's no highlighting it means that it wasn't able to load dictionaries and hence the function returns early. I will try with Russian dictionary to confirm. The delay is too much for a debug version even.

[pbek]

The delay is too much for a debug version even.

I've no delay for large notes in debug.

[Waqar144]

The delay is too much for a debug version even.

I've no delay for large notes in debug.

I get a delay of about 1100ms with auto detect (using 2 dictionaries, German and English) with a note of about 160KB and almost 3000 blocks. It used to be 3000ms before for me.

With specific language, for eg en_US, it takes, 500ms. With German, 700 because dictionary size is bigger.

This is the startup performance.

Once the application has loaded the note and dictionary, switching notes is faster.

[ivanpirog]

Thank you for reporting, I can't reproduce that on any of my systems.

I have 2 different machines with different Win 10 version (64 & 32 bit). On the fast machine delay is slightly lower.

did you build yourself or using pre-built binary?

pre-build

Can you tell us about the file size of the note which takes long to load?

Size is matter. The larger the size of the note, the longer the delay.

Can you confirm whether spell checking is enabled or disabled in Main menu- Edit -> Check spelling?

Yes. When I disable spellchecking, notes opens super fast!

Can you tell us which version of QON you are using?

19.11.12.

QON General Debug Info.txt

When I open long note I have long debug log about "[warning] Unable to find any suggestion for 'blahblah'".

It’s strange thing that spellchecking is not looking for words, but whole sentences.

[ivanpirog]

BTW, I have no spellchecker installed for russian lang.

[Waqar144]

It’s strange thing that spellchecking is not looking for words, but whole sentences.

It's trying to guess the language so that's why these are sentences.

Can you check whether you have any dictionaries installed?
Dictionaries are visible in Edit->Languages

[Waqar144]

BTW, I have no spellchecker installed for russian lang.

Even so, the guessing should work for some sentences and not fail for everything. I will look investigate this more.

[ivanpirog]

If you need more note examples, just go here and copy/paste a long article.

[Waqar144]

BTW, I have no spellchecker installed for russian lang.

Can you install a dictionary and then see if there is a delay?

Also,
In the main menu under Edit->Languages there is an option to choose a language or use auto detect. If you have installed a dictionary, can you try switching to your languages and then see if there is a performance issue.

Thank you for the link. I will be investigating this more.

Did you install a dictionary and try?

[ivanpirog]

I installed Russian lang and have no more delays!
Option: Automatic detect

No languages installed:

Ahh. So that's why.
The trigrams are failing so that's why it's taking so long.

[Waqar144]

I installed Russian lang and have no more delays!
Option: Automatic detect

Great!
If you are using only one language, you should switch to a specific language instead of auto detect. It will be even more faster.

[ivanpirog]

According to my feelings, when automatically detecting a language, notes open a little slower than if I specify the language. But it’s difficult to determine by eye, I need to measure time. In any case, after installing the dictionary, notes open very quickly.

[ivanpirog]

Ahh. So that's why.

So, the problem is detected. Congratulations! :)

Yes, auto detection is slower because it tries to guess your language. If you don't have any dictionaries installed, it will fail completely but will still try to guess language for every sentence.

Auto detection is useful when you have two languages in the same note. It will detect both languages and provide spell checking for them. (You need dictionaries for both languages)

The problem was that spellchecker should be disabled in case no dictionaries found.

The spellchecker is new, so we are still ironing things out ;)

@ivanpirog
Thank you for reporting :+1:

I have an idea. If just one dictionary installed, you should automatically set to that language. In this case the Auto detect option have no sense.

Good point.
What do you think @pbek?

[pbek]

Great work! :grin:

good idea

19.11.14

• the spellchecker is now disabled if no dictionaries are available and language
  auto-detection enabling is fixed for multiple languages
  (for #1418, thank you @Waqar144)
• spellchecker information was added to the Debug settings

[pbek]

There now is a new release, could you please test it and report if it works for you?

[pbek]

It seems that GitHub currently has troubles. I still get a unicorn on https://github.com/pbek/QOwnNotes/releases...

Waiting for 19.11.14...

[pbek]

Yes, it seems that GitHub still has troubles. I still get a unicorn on https://github.com/pbek/QOwnNotes/releases... I got that confirmed by GitHub, but they don't know when it will be fixed.

[ivanpirog]

I've checked last version for MacOS.

In the previous version (19.11.13 for Mac) there were the same delays when opening notes. In the latest version, notes open instantly. Dictionaries not installed. Build for MacOS works fine!

[pbek]

You should get a new Windows version within one hour.

[ivanpirog]

Checked. Everything works well!

[pbek]

Great, thank you for testing!
