Is there an option to copy multiple emails to the remote server in parallel?
I'm restoring multiple (tens) email accounts from MBOX files using the "ImportExportToolsNG" add-on, however when I start the copy from my computer into the email account, it copies only one message at a time, sequentially, which is a problem because the MBOX files contain large numbers of emails (thousands each).
It would be great if I can enable an option somewhere such that Thunderbird uploads several messages simultaneously to speed up the import. I'm not expecting guarantees such as "it must upload 10 emails every X/seconds" or similar, just adding some parallelism to the imports would be enough and greatly appreciated!
Thanks in advance!

No. IMAP works as it works. There are no settings other that the connections to cache, and unless you have modified that setting it will have defaulted to 5 anyway.
In a word 'no'.
It might go a little faster if you temporarily disable global indexing at options > advanced > general > enable global search
