Optimum MTU size for WP ?

[sflatt]

(I'm hoping someone techy from WP can respond to this).

I was sure i sure Slash say that it was best to have your MTU size set at 1500. Someone else on the tech forum claimed it was 576.

I've tried both and it "appeared" things run slightly faster with 1500.

So Mr Techy WP persons - is there a definitive answer ?

Yeah it was me http://www.wireplay.co.uk/ubb/smile.gif Test it yourself with MaxMtu - its freeware. I'll look up the link this evening if you want. I still stand by 576 as anything greater got broken up to send. It would be interesting to get a definitive 'tested' answer from a techie though ... http://www.wireplay.co.uk/ubb/smile.gif

You might find that TCP segments are limited to 576 bytes / segment. This is a 'feature' of some TCP implementations, but the current Microsoft stack (Winsock 2 prefferrably) will read the MTU that has been negotiated by PPP and use that (according to the spec anyhow).

Since just about all our games send packets which are less than 200 bytes it's a no brainer. We recommend a larger MTU for better net performance but I have never seen much improvement when messing with this stuff.
