659028 - Add a command line option to enable/disable preloading

Status: RESOLVED WONTFIX

(Firefox :: General, task)

Description

[Mike Hommey [:glandium]]

The options would be -preload/-no-preload. We'd need to add a telemetry probe indicating whether preloading was enabled or not.

I'm obviously not working on this, but it might still be interesting? Doug, since you've been involved with preloading recently, what do you think?

I assume this is referring to preloading specified by the dependentlibs.list file (i.e., not the windows-specific dll prefetching we do in a background thread)? I mean, it's certainly doable - what use case do you have in mind? Just power users being able to opt out of preloading?

I'm referring to what is now LibLoadingStrategy::ReadAhead. Not entirely sure it's useful to allow to disable it at runtime.
