EagleFiler is slow

Hello! I use EagleFiler to archive my emails.
I have 2010 -2023 emails archived.
I use Mac mini M1 for latest macOS and EagleFiler version is 1.9.15

Archive file is in iCloud Drive (size 6.9Gb).

EF startup is slow, about 1 minute
Open archive → try to search → beach ball 30seconds - 1minute.
If you want check old email fast, it takes 3-4 minutes to startup.

What I can try to speed up EF?

Thanks!

Does this include opening your library? On an M1 Mac, I would expect launching the app itself to only take a few seconds.

Is the beachball occuring before or after you type the search query?

What do you have selected in the sidebar?

Is your mail stored as mailbox files or .eml files?

There are some general tips here, but the more you can explain about what you’re doing the better I can advise you. Also, if you can use Activity Monitor to record a sample during the beachball that will show what’s causing the delay.
