Squid cache setup? Need some advice

Im trying to get multiple squid servers to act as front-end web servers for my main central apache web server, here is my setup so far...

I have changed the IP of the apache server that this sends traffic to, to, fyi
# egrep -v "^#" squid.conf | sed -e '/^$/d'
acl all src
acl manager proto cache_object
acl localhost src
acl to_localhost dst
acl SSL_ports port 443
acl Safe_ports port 80		# http
acl Safe_ports port 21		# ftp
acl Safe_ports port 443		# https
acl Safe_ports port 70		# gopher
acl Safe_ports port 210		# wais
acl Safe_ports port 1025-65535	# unregistered ports
acl Safe_ports port 280		# http-mgmt
acl Safe_ports port 488		# gss-http
acl Safe_ports port 591		# filemaker
acl Safe_ports port 777		# multiling http
http_access allow manager localhost
http_access deny manager
http_access deny !Safe_ports
http_access deny CONNECT !SSL_ports
http_access allow all
icp_access allow all
http_port 80 accel defaultsite= vhost
cache_peer parent 80 0 no-query originserver name=myAccel 
cache_peer_access myAccel allow all
hierarchy_stoplist cgi-bin ?
cache_dir ufs /var/spool/squid 2000 16 256
access_log /var/log/squid/access.log squid
cache_log /var/log/squid/cache.log
acl QUERY urlpath_regex cgi-bin \?
cache deny QUERY
refresh_pattern ^ftp:		1440	20%	10080
refresh_pattern ^gopher:	1440	0%	1440
refresh_pattern .		0	20%	4320
acl apache rep_header Server ^Apache
broken_vary_encoding allow apache
always_direct allow all
coredump_dir /var/spool/squid
This works wonders.. for about 4 minutes. then the requests go from 2 seconds per a page load, to 5 to 10, then it wont even process, the tail -f access_logs shows that its not even hitting apache any longer on the central server, so its like squid freezes up, any idea???

I have turned off the firewall on the squid server as well as the central apache server, and still doesn't help much. I read through and did all of it, with no avail.

I have attached the 2 images of load times with and without squid from internetsupervision, just to give you an idea of the load time

P.S. I doubt this is a connection issue between the servers, as the website WITH squid loads just as fast as apache for a few minutes, then slowly goes to a hault
