My question is how do i optimize the containers so the load average will be back to normal instead of the high load i am facing right now

First, memory has nothing to do with load average. Take a few minutes and read up on the difference.
Read all the linked reference material. It's important.
This answer will still be here when you're done.


You're back? OK good.

Now, what you need to know is this: High load isn't a problem.

Poor performance is a problem.
Crashes & freezes are a problem.
Running out of disk space is a problem.

If you're not having an actual problem don't obsess over the load number.
From a business standpoint the higher the load number the better -- If a system is operating well (that is, nobody is complaining) with a load average of 1000 then you're making efficient use of the system.
Note that I'm making a distinction between computationally efficient and efficient from a business standpoint.


If you are having an actual problem, like poor performance from the VMs, load average is one diagnostic tool to help you troubleshoot it (an indication of how many processes are waiting for the CPU).

You probably can't optimize your way out of this situation by tuning the VMs -- your system is demanding more work out of the CPU than it can do. A load average of 300 means you have 300 processes that want to be using the CPU (versus however many cores your system has), and that could very well mean the wait time is noticeable.
To correct this situation you need to remove load from the server (by migrating work - VMs - to another box). Start by migrating the "heaviest" VMs (the ones that need the most CPU time), and keep removing load until the system performance meets your needs (regardless of the load average). Remember to leave yourself a little headroom in case the VM workloads change.

(For that matter if you aren't having problems but just can't get past having a high load number this is still the solution - remove load until the number makes you feel better.)
