Thank you for your reply. I have not found an issue the hardware. Atop shows everything in normal ranges. I do know the squid is about 50% faster with our filter set up as a parent vs routing through it normally. Not sure why that would be. However, when I set it up as a parent I notice quite a few connect to parent ip failed. There does not seem to be a network issue.

It is often very difficult to solve performance problems on the mailing list, but that does not imply folks should not ask performance questions. over time it slows down significantly. In case nobody looks for or finds problems in your configuration: What is the bottleneck? CPU? RAM? Disk I/O? NIC interrupts? A tool like atop may be able to answer that question for you, especially if you let it collect stats from before Squid start to the time when the Squid becomes very slow.
