funnily enough, after I changed Basic Mode's Node from specific server to Auto Selection,Realtime RTT seems to be working again.
Though I think Auto Selecting the node made the overall connection really slow.

:-) It's a known issue at v4.3.15 if FastConnect mode turned on. I hope it'll be solved sooner or later. If you'd like to see exact RTT graph, as workaround you should disable FastConnect mode.

Yes it's also one of high prority task at next release. :-( At this moment it takes more times whenever no. of mudfish nodes are increased.

I see, thanks for the quick reply.
Basically I should disable FastConnect mode, and always choose a specific Server Location (instead of Auto Selection) in Basic Mode for optimal performance.

Excuse me for asking more (and longer) questions:

1. In [Basic Mode -> Magnifier -> All-In-One], I noticed how the RTT values of the same server of the same item would spike up to 100ms. The strange thing is that the graph itself doesn't change its shape; from what I know, the values of RTT Graph should NOT change since they are the records of the past values. Though the values would always return to normal a bit later, I find this situation confusing to manage as it would momentarily raise my selected Node's 'Score' value to extreme forcing me to reselect a Node everytime it happens.
I'm anxious whether if this is impacting my Mudfish experience or not.

2. I'm currently choosing the optimal RTT Server Location by constantly looking for servers with lowest scores in [Basic Mode -> Magnifier -> All-In-One]. From among the top 5, I would choose a server with the least (+stable) amount of: RTT fluctuations, Traffics and System Load. Are these methods appropriate for the best Mudfish performance?

3. I'm wondering whether choosing a Server Location geographically closer to selected item's Game Server Location impacts Mudifsh performance by an unforeseen amount or not.

Cheers

Here is my answer for your questions:

1. At popup window (open when you click the maginifier icon), you can see three section; 1) from your desktop to mudfish node, 2) from mudfish node to game server, 3) All-In-One. And normally score is calculated with formula: sum of 1) and 2)'s RTT avg and stddev. If there are any graph spike or it looks something wrong. Please check other section 1) or 2). I hope there's no issue to fetch information from server daemon but it looks sometimes it has a connection problem leading to wrong score value. Yes depending on which node you picked your experience could be different.

2. Yes I think so. We have a small document for this case; FAQ - Nodes

3. Even if you pick a mudfish node near to game server, depending on its ISP peering, RTT could be different. We have a ping test interface from mudfish node to game server at http://ping.mudfish.net/ so you can try to send a ping by hand and see to result.
