I have triggers that manipulate and insert a lot of data into a Change tracking table for audit purposes on every insert, update and delete.

Not that I know of, but are you inserting values into the Audit table that also exist in the base table? If so, you could consider tracking just the changes. Therefore an insert would track the change time, user, extra and a bunch of NULLs (in effect the before value). An update would have the change time, user etc and the before value of the changed column only. A delete has the change at, etc and all values.
Also, do you have an audit table per base table or one audit table for the DB? Of course the later can more easily result in waits as each transaction tries to write to the one table.
