intra-jail communication slow

[Beeblebrox]

I would like to know if this is normal for jails:
1. 3 different Jails for mysql , http, tinderbox.
2. No pf / nat running for the time being
3. My ifconfig for jails:
	inet 192.168.2.1 netmask 0xffffff00 broadcast 192.168.2.255
(tinderbox, dhcp, tftp)
	inet 192.168.2.100 netmask 0xffffffff broadcast 192.168.2.100  (http)
	inet 192.168.2.101 netmask 0xffffffff broadcast 192.168.2.101  (mysql)

Problem: Jails seem to be communicating with host and with each-other
at an observably slower rate, compared to when all services are
host-based.

Is this normal for jails or is my netconfig problematic in some way?
