These are all separate from the issue reported in the thread

There is a network problem that occurs under the condition where enough clients are in a zone and one or many have not so great connections our server network code will resend very aggressively which results in a server with a lower CPU frequency such as a Xeon 2.3Ghz to essentially choke itself from the rapid burst of resend packets.

The resend packets are choked primarily by compressing packets and sending them over the line at a rapid rate and the CPU will max out for that thread and can take several minutes to recover from

Correcting the resend logic is a complex issue because we use dynamic algorithms for resend rate and packet recovery that has to take in a lot of different factors.

We have some ideal settings figured out and are looking to get them pushed to mainline as soon as we feel confident that they don't produce any more regressions
