Not sure if this is related, but I have seen more squid errors than I've
gotten before.
It's not related. Squid error messages are what you get when squid is
working and something else isn't. When squid isn't working, you just get
timeouts or refused connections, it's left up to the browser to report
an error to the user.
The something else that isn't working is typically a segfault in PHP or
APC, which squid reports as ERR_ZERO_SIZE_OBJECT.
If squid is pushed over its capacity, the result is poor page view
performance, although there's half a dozen things other things that can
cause that. Identifying a system bottleneck can be a complex task.
