Different Ping Speeds Between Win2k ---Winxp

Just installed a dual boot machine late last night and when I got home from work this afternoon, I noticed something curious...ping itmes differ widely between win2k ---Winxp and Im stumped as to why...





1) These installation are completely fresh with no tweaks made etc and are both running all latest service packs

2) I have a 2mb plus.net account

3) The above example pings were performed within minutes of one another

4) I use a Netgear dg814 router (default 1458 mtu on router)

5) DrTCP does not show any specific setitngs (boxes are blank).

Im not sure why there is such a noticeable difference between the 2 operating systems, my only preusmption is that default mtu/rwin settings are different between the operating systems, which is affecting the ping times.

However Im not sure of the default settings in the 2 operating systems so I cant verify this.

Anyone else experienced this or now the reason behind this anomoly

MTU/RWIN settings will not effect ping times.

I can't remember if it was Me or Win2K that reports the wrong ping times. Maybe that would explain the difference. XP does report the correct timings.

Its ME that reports wrong ping times. But yes, XP is far less efficient than any other Operating System (apart from 2003 - I havent tested that one yet) at ping times. Reported ping times are generally higher, although if your playing games etc, they will probably be unchanged.

It is normal - if not somewhat annoying.
