NIC MTU size 1500 (default) vs 9000 (jumbo)

What is the recommended frame size for client connections to ZoS' NA Megaserver?

Thanks in advance

Are you trying to improve something?

1. You can change the size of network packet frame send by your computer to the NA Megaserver, only. But more data is downloaded than uploaded.
2. Jumbo frames do work, if all network components between your computer and the NA Megaserver support jumbo frames, only. But most likely your ISP router does use a MTU of 1500 already. So, the jumbo frames get fragmented anyway.

But hey, who knows. You can search for "tcp optimizer" and try "Largest MTU" of "MTU/Latency".
You have to find out the IP Address the eso64.exe is connected to, e.g. using the "Resource Monitor" from the "Task Manager".

Thanks, but was wondering if ZOS or Bethesda already commented on this, e.g. sticky post for 'optimal tuning'.

Curious to know if ZOS has identified a bottleneck at their enterprise demarc/router/switch/NIC or if there's an exceptional queue length for processing our packets at the CPU/bus lane.

Again, thanks.

Only your ISP can answer this question, as the MTU Setting must be consistent at all hops in the path.

It is doubtful that Jumbo Frames would work, as that is usually only set on Ethernet or Layer 2 Circuits, not IP or Layer 3 Circuits. At least I have never set it on an Internet Circuit I have designed or configured or installed for anyone, and I have been doing this for 20 years now.
