Very bad performance 4.0.0 compared to 2.23.2

Already a date when the 4.x version with normal performance will be available.
I am still stuck with version 2.23.1 because of the terrible performance of versions 3.x and 4.x.

Kind regards,
Peter

May I ask what Joomla version you're using? I am seriously considering rolling back to 2.23.2 since I have attempted versions 3 and 4 installs on Joomla 4 and neither seems to work all that well - load time is extremely slow when the calendar view is loading, and then it doesn't show any data. I have a Joomla site on 4.4.13 and I purchased this product in April and have yet to be able to use it. 

Hi,
We will release new OS Services Booking version soon (within this month) to solve the mention issue
Thanks

Hi, I am using the ossb 2.23.1 version on J4 and J5 websites.

I was able to address the cause of the bad performance of ossb 4.0 and Dam and his team solved it on my test server.

So in the next version of ossb this problem should be solved.

Sure, Peter
