Using the Mail app (macOS) with a Gmail Account and pressing the refresh button, makes the app hang in "Checking for Mail..." for 20-30+ seconds. It is faster quitting and opening the Mail app to check for new mails.

There is a memory leak down the network stack (probably within security library/ TLS layer) that has been reported over 6 months ago but has yet to be fixed. Depending on the app's network usage this is leading to several GBs of leaked memory per day.
