Question : Small ping sizes slower that larger ping packet sizes

When I ping between 4 pc's i get an 10ms reply (a normal 32byte ping)

That's not normal. 1ms is what I see most often.

But when I use a packet size of 4000 or even 8000 (ping computername -L 4000) I get a response time of 1ms

How can that be? Do I have some network performance issues here or what?

Answer : Small ping sizes slower that larger ping packet sizes

I think this has to do with the fact that if your packet data frame exceeds your MTU (usually 1500 bytes - 28 bytes for the frame header = 1472 bytes) and therefore it automatically gets fragmented... as a result the smaller fragments arrive faster? Try playing with the "-f" switch in your ping command...
