Those numbers are common for a shared dual-core web server. Mine tends to run about that hard with 50% idle cpu. Currently 4.34, 5.72, 6.26 The old tuning theory of < 1.0 doesn’t appear to be as critical with multi-core CPUs as it did in the old days. It’s also not reasonable to expect < 1 on a shared server.
I’ve not got a reading on the DB servers because I don’t have a shell login to the DB server. (remember that MySQL runs on separate machines from web servers.) If you’re concerned about DB performance, you can submit a ticket specifically about th DB to ask a DH DBA to take a look at it.
