|  | 31 | # Rationale: speed has a lot of dex code expansion, it uses more ram and space | 
|  | 32 | # compared to quicken. Using quicken for shared APKs on Go devices may save RAM. | 
|  | 33 | # Note that this is a trade-off: here we trade clean pages for dirty pages, | 
|  | 34 | # extra cpu and battery. That's because the quicken files will be jit-ed in all | 
|  | 35 | # the processes that load of shared apk and the code cache is not shared. | 
|  | 36 | # Some notable apps that will be affected by this are gms and chrome. |
