slow response of the realserver

First of all, I am an absolute newbie, pls don't hesitate hitting me hard if I 
am asking a stupid question ;)

I have successfully setup my first LVS-NAT environment, consisting of 3 boxes. 
2 of them are running linux w/apache (lvs1 and lvs2), and the third one is 
running winxp w/ tomcat (lvs3). All three boxes are acting as realserver, with 
one linux box (lvs1) acting as the director also, using the localnode method. I 
am using the "configure" script, with the NAT_ONE_NIC_TWO_NETWORK template.

Basically, this setup is working fine, as clients would connect to each of the 
realservers in turn. But the problem is, if a request is being dispatched to 
lvs2, which is a pure realserver, there will be a few second's delay before the 
connection is made. On the other hand, requests dispatched to lvs1 and lvs3 
don't have this problem. 

I also tested them with telent. The problem is about the same, the login prompt 
will not pop up until after 5 seconds, but after that, the connection speed 
seem to be the as fast as that on other realservers.

I read the mini-howto, there is some related info at the end, but I think I 
still need some more help.
