How to reduce the load on CAS server

I am having SCCM 2012 SP1 CU3 environment. CAS is broken with its primaries on replication often.

Looks like, its handling more messages for an hour (arround 82k messages)

Is this a normal thing which can be ignored? and how to reduce the load on CAS server?

Do you have 100,000 clients?  If not, the absolute best answer is to Migrate from your less-than-efficient, should-never-have-had-a-CAS hierarchy to a Standalone Primary, and use Sender-capable DPs in the sites where you've put Primaries.

If you DO have 100,000 clients (or more) then I suggest finding a consultant firm which has handled designing and making recommendations for a  site of more than 100,000 clients.  There are multiple ways to design (or re-design) with a CAS and primaries, but there are considerations specific to your company which may make a 'random recommendation' on a forum like this leading you to a completely horrible destination--which could make your issue with replication WORSE.  So I don't think we want to go there, in a forum.

I have 76000+ machines in my environment and we have a CAS server considering future expansion. 

Looks like, I need to opt for Risk assessment program (RAP) from Microsoft?

my guess is you're going to have a hard time fixing replication issues on a forum, you should contact Microsoft.
