[Resolved] Views taxonomy cache very slow

Hello,

While analyzing performance issues using XDebug profiling I noticed that Views needs very long to build up the taxonamy cache.

It seems, that it is loading and processing every single term from the database.

Thanks,

Hi Adrian,

Thank you for getting in touch.

We are constantly improving our Views/Blocks plugin so that it can run faster and smoother for our customers.

Can you let me know what kind of view is this ? Also does this only occur when you first load the view up ?

Please let me know.

Thanks,
Shane

Hello Shane,

The view is a search view with filters.

This seems to happen on every request. At least in my profiling.

All other caches are fast, only terms.

Hi Adrian,

Thank you for the information. I assume that this is normal for now, however our team is constantly working to improve this functionality.

I also believe that this could be due to the setting on a view where you can only allow the view to show options that will produce a result.

Do you have this option enabled? Also are you experiencing any slowdowns of the site on the frontend itself ?

Please let me know.
Thanks,
Shane

Hello Shane,

Thank you.

Yes we have "Show only available options for each input" enabled, disabling this options really improves page loading times.
I will speak to my client, if this would be an option.

Edit: A good tradeoff would be to enable/disable this on a per-filter basis. I.e. we have 10+ taxonomies, but only would need about 2 or 3 to be already prefiltered

Thanks,

Adrian

Hi Adrian,

With the "Show only available options for each input" live queries are done to ensure that only the options that will produce a result will be available. This can have a speed impact as you can imagine you will need to pull all the items and check the post database in order to return only those options.

Hopefully your client will agree to have this option disabled. There will be some tradeoffs as the "Show only available options for each input" is far more complex than just leaving it disabled.

Please let me know as soon as possible.

Thanks,
Shane

Hello Shane

We disabled the option for now.
Not a real solution, but a valid workaround for us.

Thanks,
