Just an extract from the blizzard blue post:
"We have been seeing a lot of confusion regarding some of our recent changes to the User Interface, specifically in regard to the new in-game latency meters. With 4.0.6, we have split the two separate connections the client forms to our game servers into two different ratings, labeled 'Home' and 'World'."
"In essence, 'Home' refers to your connection to your realm server. This connection sends chat data, auction house stuff, guild chat and info, some addon data, and various other data. It is a pretty slim connection in terms of bandwidth requirements.
'World' is a reference to the connection to our servers that transmits all the other data... combat, data from the people around you (specs, gear, enchants, etc.), NPCs, mobs, casting, professions, etc. Going into a highly populated zone (like a capital city) will drastically increase the amount of data being sent over this connection and will raise the reported latency.
Prior to 4.0.6, the in-game latency monitor only showed 'World' latency, which caused a lot of confusion for people who had no lag while chatting, but couldn't cast or interact with NPCs and ended up getting kicked offline. We hoped that including the latency meters for both connections would assist in clarifying this for everyone."
Ok, so, at the end of last year, MWEB was completely broken with regards to whats mentioned above. I would be able to chat in gchat, but I would have 20 second lag just trying to mount up or farm a node or anything. Since around Christmas time, mweb has been working a charm. (176ms - 250ms) No proxy. No VPN. No nothing. Just a good old uncapped/shaped account on a 4mb line.
I would suspect if you are having this latency, its due to (as Blizzard stated) one of the following issues:
"Here are the most common causes of high pings/latency (on both Home and World):
* 1) Wireless
* 2) Packet loss
* 3) Almost-but-not-quite-broadband*
* 4) Addons (yes, those wonderful UI modifications)
* 5) Firewalls (some firewalls do interesting things to latency... try playing without it to see if it helps!)
* 5) Mis-configured or defective home routers (please temporarily bypass before anything else)
* 6) Quality of Service and Traffic Management Systems performing packet queuing of some sort.
* 7) Net link saturation (not necessarily your ISP, but somewhere between you and Blizzard)
*As of July 2010, the 'official' definition of Broadband Internet (per the FCC) is '4Mbps downstream and 1Mbps upstream'. Anything lower than this is not 'officially' broadband."
Best you get your line re-synced. If you are running on a 384/512 line, expect latency. And make sure your ISP knows what they are doing.
Good luck.
