can you post real-time stat screen shot and Server->Security settings screen shot.
high load is a issue, should fix it. but again please be aware: your have 32 CPUs, so load 32 or 64 should not be a big surprise comparing with 1 or 2 CPU system which load is 32 or 64 too. 32 or below is quite normal.
except load, please pay more attention on the actual website performance. if load faster, more traffic will come, which lead higher load. also pay attention to the WaitQ as mentioned before.
