TIME_WAIT looks OK to me, it's not high. Here are some hints for sysctl

NOT set tw_recycle=1 though!).
Regarding half the traffic, just check whether you have failed requests
(e.g. "varnishncsa -m TxStatus:[45]" or similar), but it can be due to
the way Varnish handles keepalives differently (what are your Varnish
vs. Squid settings for Keepalives?).
