Using quicken for shared APKs on Go devices may save RAM. 31# Note that this is a trade-off: here we trade clean pages for dirty pages, 32# extra cpu and battery. That's because the quicken files will be jit-ed in all 33# the processes that load of shared apk and the code cache is not shared. 34# Some notable apps that will be affected by this are gms and chrome. 35# b/65591595. 36pm.dexopt.shared=quicken 37 38# Default heap sizes.
