much longer calendar index time vs web app

Hello, I have a little over 1.1k calendar appointments in Proton Calendar. In the web app, enabling indexing takes less than a minute until a search can be performed. On the electron app, it takes over 4 minutes for the indexing to be completed. Since new appointments also need to be indexed on the fly, my guess is that this always takes more CPU time in the electron app vs web. Maybe this can be improved. Thank you!

btw. I did not check the mail index times yet, but if the code/algorithms are similar, then this may be the same behaviour there.
