How are things looking today? We found an issue with some Path MTU
responses or something getting lost, causing TCP connections to
constantly scale back. We've temporarily dropped the MTU on our host
machine from 1500 to 1470 which has yielded much faster performance in
our testing over the last 12 hours. Let me know if you're seeing the
same.
