13 secs still sounds a bit high, but obviously much, Much, MUCH better than what you were seeing before.
Improving on the compilation time will likely mean tracking down, and working on, the query(s) requiring the most time to compile. Chances are you could tune that particular query (eg, force allrows_oltp at the query level, simplify the query) such that you can still run the proc under allrows_mix/allrows_dss and still get a fast(er) compile time.
----------
Nothing major jumps out from the config file ... and I expect any more improvements in compilation time will come down to tuning/simplifying individual queries.
