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