I dont like your 2.5% IO waiting, this may be reason but need to guess what
process.

try this:
disable your arpalert when much servers connect arp daemon has much more work
to do.
i guess you are using squid27, so change your logging, use syslog instead
writting directly to disk (syslog has cache) or even better if you dont mind
turn off logging and try
