A bit slow of validating license key

Dear Sir/Madam,

I add the license APIs to validate the customer’s key.
However, we found out every time a validation is needed, it kinda has a big delay, for example, we check the key and pop out a configure window, and there is a delay between.

Please could you kindly advice (maybe a quick solution is to configure some settings for protection).

Regards

thanks

We can offer to use “Level=Maximum speed” at options tab.

Thanks.
The RSA 2048 is slow,
is there a quick way to change it to RSA 1024? I couldn’t find the options to configure.
