In this case it is a Snapdragon 410 (1,2 GHz quad core) paired with 2 GB or RAM and Android 4.4.4 on a 720P screen. However, just hardware performance can be pretty much excluded as a cause. Not only do smaller inboxes with an equal amount of messages displayed (so the number of messages phone side should be equal) have no issues, two other mail programs have no trouble running the same large mail box without any lag. If anything at all, there are some settings somewhere that cause an insubordinate amount of processing to be done. This phone can and should run this workload with absolute ease and, in fact, it does run it with ease. Just not in K-9.
There is a rather high number of unread messages, I am not sure that might make any difference.
