On 11.4 and 12.2, loading the initrd takes just a handful of seconds (if
at all), barely noticeable compared to the remaining boot process.

Compare the sizes, I'm pretty sure this will shed some light on the issue.

Yep, your right. In our configuration, the initrd of
11.4 is 11MB
12.2 is 17MB
12.3 is 32MB

Hm, well then I guess there is nothing to be done about this delay?
Is grub2 any faster than grub loading the initrd?

The size difference between 12.2 and 12.3 may be due to having debugging enabled for the RC version.

On my 12.3 system, initrd for 3.7.9-1.4 is 33 MB. I'm actually using 3.9-rc1 from the wireless-testing repo with an initrd size of 37 MB. With grub2, it loads in 2-3 seconds on an HP dv2815 laptop with a modest AMD Turion CPU at 2 GHz.

The difference might be grub2, or it might be due to poor performance for an i7 running in 8686-compatibility mode. I doubt that Intel spent much time optimizing those operations.
