Thunderbird sucks on new MBA

[phl92]

Okay, so for the first time I tried a dedicated Mail App to check my mails. The reason is I don't have anymore only Gmails in use, but also other Mail accounts, and my workflow requires constant switching.
So I tried Thunderbird.
After installing and setting up all my 5 accounts, I saw the Mac was quite under load, performance dropped and energy was going away like on a old Intel Macbook. I saw that Thunderbird was downloading around 55000 Mails from all my accounts.
In the meanwhile this took a while (and is still not finished) I pressed several times "compact Mails" but Thunderbird still takes up from 1,2 GB to 2,4GB of my Ram!! And also my Energy drains like crazy.

So do I have wrong settings to run Thunderbird?
Is thunderbird old and a bad choice? Why does he need to download all Mails? I don't want them necessarily offline on my Computer.

Before people recommend other Mail Software: I don't want to pay for Outlook and I don't want my data to be sealed (Sparks). Any other Mail Software <20$/year would be ok.

Let it run overnight to finish what it's doing. How long should it take to download those 55,000 messages?
(What's the total size of mail stored in each account?, etc.)
What kinds of accounts, and what settings?

This might be a stupid question, but why not just use the Mail app in the OS.

Well I find the Mail App of Apple very bad. Emails take forever to get in (no push) and I heard from people that it sometimes deletes mails, its just not reliable of what I have heard.

Each account is around 1-10 GB in average around 3. So about 15 GB but its all the time donwloding something never ending. I use Imap/Smtp

How long should it take to download those 15GB / 55,000 messages? Mail servers generally don't serve mail at line speeds. [Edit: Never mind. Clickbait thread. Bye.]

Where are you getting this information from? Apple mail has push notifications, you can set it to auto 5, 10, 15 etc or customize the push. I'm running the Mail app in the background (macOS Big Sur) and when an email comes in I see it on the Mail app icon or in the notification center. In fact push notification for the stock Mail app almost happens instantaneous. I have never had the Apple mail app delete my emails, never.

When you say each account is 1-10GB are you referring to disk space or memory? Mail takes up 80MB of memory and I don't have it taking up GB's of storage space because I would know.

Here in the forum is a big thread about the Apple Mail App, its not my opinion since I never used it on MacOs just on iOS it is unusable for me
