Hi, Blagoj 

Firstly, I would like to sincerely apologize for the delayed response as we have been experiencing an unusually high number of tickets. I am sorry that it has taken longer than usual to respond to your concern and your patience is highly appreciated.

I see what you mean, i watch the Network Tab during load, and it went for 5.5 seconds for the table.

The loading speed depends on a lot of factors - your hosting plan, server's performance, amount of other data on the page, internet speed, etc. 

For example, you can take a look at the table on our documentation, which contains around 2.600.000 rows, and see how it loads. 

The more data the table has, the more chance that it will impact the loading time.

Hi, Blagoj

No problem, i am happy to help.

I just wish to add something.   Along with other details I mentioned that can affect the loading speed,

i also had a couple of cases with users who have an "optimization plugin".

For example, some hosting providers like to install their own optimization plugins, such as 'SiteGround Optimizer', for example.

These plugins have certain settings that can negatively affect the performance of our tables.

If there is any JS minification going on,  or perhaps caching, there can be other settings, I can't say exactly,

but something to be aware of.

If you wish to do some troubleshoot testing to check if an optimization/caching plugin might be slowing down tables,

you can try to disable all plugins and just leave wpDataTables - then clear all cache and reload the page, see if it is faster.

Then, if any optimization plugin Is used, try to revert all settings to default, and try to exclude caching for pages where you have our tables. ( If you use server-side tables like SQL or Manual)

That is about all the advice i can give about this,

but of course, let us know if you have additional questions. Thank you
