Accordion slow rendering

I primarily use Accordion for listing (instead of table).
I know it is not the best way but I like how it looks and that’s why I bought the Pro version btw ??
The problem is that when I have 50-100…+ entries the accordion takes a hell lot of time to visualize. Can it be possibly related to high DOM count? I think that might be a reason for some browser hangup while rendering… but I feel it too long.
Honestly, I don’t know whether the plugin itself is slow while generating output (it certainly does a lot of scripting inside), or the browser (I use the latest Chrome for testing) takes this very long time to render. Do you have any idea? ??
Thanks
