Of course if you need to cross reference the entirety of a gigaproject like Chromium you're going to need some sort of a cache and smart search. If I was a Chromium dev I'd probably set something up to help with that.

99.999% of source trees are a tiny fraction of that size however.

As I mentioned in another comment I routinely hack in the Linux kernel which contains about 15million SLOCs (per sloccount) and ripgrep takes less than 5s on a cold run and is near instant after that. ctags lookup almost instant regardless of cache. And that's on a 5 year old middle of the line SSD and CPU.

Inability to easily deal with chromium-sized repositories out of the box might be a deal breaker for you but it's a total non-issue for me.
