gmail IMAP extremely slow

[jeff....@gmail.com]

Recently I did a "checkup" as offered by google for account security. I disabled "less secure" apps and then realized that Thunderbird was included in that list so I enabled "less secure". Since then, the IMAP performance on all my platforms is poor, it now takes minutes to login and/or send mail. This has persisted past the last thunderbird update to 52.5.2

Any ideas on how to alleviate this or has google decided to degrade performance on "less secure" apps?

In my experience of using gmail imap with Thunderbird (for many years
now), it is extremely slow. People suggest unsubscribing from the All
Mail imap folder, which can be very large. However, I've never found
this to make any difference to the speed in accessing emails in other
folders/labels. In any case, I like having the All Mail folder
available as it's useful to be able to filter through all my emails
sometimes.

All I can say is that on my iPhone email app, there is never a speed
problem using my gmail account, even the All Mail folder, suggesting
that the problem may lie with Thunderbird rather than with Google.

I now only use it for newsgroups, but it is very slow.

Do you have "Allow immediate server notifications when new messages
arrive" enabled in your Gmail accounts server settings?

What is the "Check for messages every" set at?

Do you have "Check for messages at startup" enabled?

Why do you have Thunderbird set as a "less secure" app? Are you not
using OAuth 2 as your Authentication Method?

This morning it didn't load fully the firs time I tried. Fortunately it
did later.
