IIRC, Squid code is not optimized for handling a large number of cache_peers: Several cache peer selection steps involve linear searches. I do not know what exactly causes high CPU usage in your environment but it could be those linear searches. You can test that (indirectly) by decreasing the number of cache_peers from 5000 to, say, 5. That is a weak test, of course, because other cache_peer-related overheads could be to blame, but I would start there.
