There is a 6 month process for the express applicants and this applies to 80% cases
during this time
they check your medicals, background and do a security check..
all of this takes a while and if everything goes smoothly you get a PPR request within the given time frame aka 6 months
There is no way to speed up the process.
You can order GCMS notes once you're in the end stages of the 6 months these notes give you a good detail of what is happening with your file but ordering them at an early stage won't do any good. Also they take 30 days to process those notes too.. so sit back relax and continue doing what you're doing worrying about it right now won't speed up your process any faster
