I have gathered data from the last few days after adding the new server. There could be various reason for this such as:

1. The VPS host is at full capacity during peak hour. Yes we are not on dedicated VPS yet, we can't afford it anyway with our current player base, it will be like throw money down the drain. We have observed most hunt session during off-peak time is not affected. Our main server CPU usage during peak time is average around 70%-85% while our network usage on 2 Mbps/s to 3 Mbps/s.

2. Client/Server Limit; This is probably other reason why most Nexia/Nexus server limiting party member not more than 15 members. The Client/Server is probably just could not handle frame update with lots of action in one screen, The server then respond with start dropping the connection on lagging or freezing clients. This is also why most server won't allow multiple client on same computer.

While I don't see such issue occur when our limit is still at max 15 party member. Since we started monetized the party slot this issue happen more and more with our increasing AFK clients lately.

Here is a few option for our short term solution while I am finding for the long term solution
1. We will start by limiting maximum connected client per IP from unlimited to 2 client only during peak time or during double exp hour is active
2. Disable additional max party slot. We will keep the limit on 15

Our long term solution will be adding new server and split the server into 3 dedicated area Trowulan, Buya and Nara, Our core team has manage to split the server into 3 separated area, the issue right now is they just can't make it to communicate each other YET. Anyway we can't add another server to implement this yet not until our unique user base is increased and our issue with multi server link is resolved.

So we will start implement short term #1 solution to see the result if the result #1 is not good then we will implement #2 solution.

Thank you
