Correct build flags

[Niranjan Rao]

Greetings,

I did my local compilation for version 109.0.5414.74 on Ubuntu. What I am discovering is my build slower by magnitude than the one installed using operating system installer. Rough observation shows my build uses higher CPU also.

My theory is wrong or missing build flags. I did follow steps at https://www.chromium.org/developers/gn-build-configuration/ and this is how my args.gn file looks like. Are these right flags to use for the release build?

is_component_build = false
is_debug = false
symbol_level = 0
v8_symbol_level=0
enable_nacl = false
blink_symbol_level=0

enable_linux_installer = true
#is_official_build = true

Regards,

Niranjan

You should set is_official_build to true. Why did you comment it out?

I commented out because the page https://www.chromium.org/developers/gn-build-configuration/#official-chrome-build, says you need to be googler and refers to src-internal. Last time I tried enabling it, I got some errors, right now not able to recall.

Regards,

is_chrome_branded is what's Googler only, official build is mostly optimization level stuff and some behavior you'd want in a build released to users.

That is misleading; is_chrome_branded is for Googlers, but
is_official_build is what you should use for something to ship to
users. It should work fine.

Although the linking process for an official build can be very CPU and memory intensive. Possibly even more so with PGO turned on. The referenced doc also explains how to turn PGO off.

I'm not 100% sure and I didn't check, but the PGO data may not be public. See docs/pgo.md for more info.
