Terribly slow draft save

[chemi]

Dear all.
I hope this is the right place to let this message. Sorry if it is not.
I would like to know if any of you have experienced a high delay in the draft save of the messages. It does not matter if it is an autosave or the draft is being saved by pushing the save button. The fact is that it takes a lot of time to have the draft saved.
I have experienced this behavior in docker roundcube versions connected remotely to the mail server. It is not mail server dependent as it has happened in different mail servers. On the other hand, receiving or sending messages have no delay.
I would appreciate any comment about this issue.
Thanks and best wishes.

I haven't seen any problems, try enabling imap_debug and posting the log when you try to save a draft.
