Q: Lag in Typing in Yosemite's Mail w/ External Apple Keyboard

Since upgrading to Yosemite I have been having a very annoying problem with delayed typing response in Mail when I have my external USB Apple keyboard (current model with numeric pad).  It is a sporadic issue.  Typing will be responsive, then there are 2-4 second delays in response.  I have only witnessed the issue with Mail and when using the external keyboard.  Problem does not occur in other programs or when using my MacBook Pro's built in keyboard.  Nor did the problem exist prior to upgrading to Yosemite.

 

My equipment is a late 2013 MacBook Pro Retina.  When on my desk, I have it connected to a 23" Apple Display (original LCD), USB Apple Keyboard, Logitech cordless Trackman, and a Drobo firewire external drive. 

 

Has anyone else witnessed this issue?  Or have an suggestions on correcting?

 

Thank you in advance!

MacBook Pro with Retina display, OS X Yosemite (10.10), Mail

    This issue resolved on its own long ago for me.   I had switched to Postbox to get away from the lag bu don't need to use it anymore.  I haven't updated to El Cap and one of the reasons I'm not going to for awhile is to avoid any risk of having this annoying problem return.

    Been having this problem intermittently since 10.10.5 was released. None of these other fixes worked for me.

     

    However, I finally narrowed it down to replying to long-chain message threads. New emails don't have any lag. Replies to a thread of 1 or 2 messages don't have the lag.

     

    When I reply, if the message has a lot of other embedded replies (say, 30), the lag happens. I've started deleting a bunch of the embedded message history in the reply and the result is that the lag disappears. I think that there is a bunch of time reformatting the long reply trails as I type each character and it is choking on that.

     

    I'm working around it, but I have at least something that works. Go figure.
