For those that are interested:

I have added a new option to Jamba - Core: Communications called "Boost Jamba to Jamba Communications**". Basically it changes the settings in ChatThrottleLib to be faster at the risk of disconnections... The option will be on be default but you can turn it off.

PHP Code:
function AJM:BoostCommunication()
    if 
AJM.db.boostCommunication == true then
        
-- 2000 seems to be safe if NOTHING ELSE is happeninglet's call it 800.
        ChatThrottleLib.MAX_CPS = 1200 -- was 800
        -- Guesstimate overhead for sending a message; source+dest+chattype+protocolstuff
        ChatThrottleLib.MSG_OVERHEAD = 40
        -- WoW'
s server buffer seems to be about 32KB8KB should be  safebut seen disconnects on _some_ serversUsing 4KB now.
        
ChatThrottleLib.BURST 6000 -- was 4000
        
-- Reduce output CPS to half (and don't burst) if FPS drops below this value
        ChatThrottleLib.MIN_FPS = 10 --was 20
    end
end 
Edit: And if all your toons are in a party - pushing settings and other comms functions are a lot faster, including the quest watcher.
