Any tips to speed up compilation time?

[Al Mo]

Title is self-explanatory,

Every time I change a bit of code I recompile and goes through everything again ... it takes about 20 mins. to complete,

Any ideas on how to speed this up (if possible)?

If mksnapshot is taking a long time, you can set v8_enable_fast_mksnapshot in gn args. If you set up your initial build using gm.py, it would helpfully set some values to make debug builds faster (https://source.chromium.org/chromium/chromium/src/+/master:v8/tools/dev/gm.py;l=125;drc=fb3da4ec8db4975f988b2fdf53cc97290c8f46c9)

If you are a committer you can also sign up for to have early access to Goma (https://chromium.googlesource.com/infra/goma/client/+/HEAD/doc/early-access-guide.md)
