Could you explain why the lag isn't present on my Desire HD? And yes, it does go into deep sleep.

What's even more annoying is the two seconds it takes to turn on the screen to hang up a phone call. Again, the DHD turn on the display instantly.

These issues aren't a deal breaker for me but they're annoying.

I don't know if this has been discussed already (since I can't bother to read through the entire thread) but from what I've read and gathered the issue lies within the CPU cores. When the phone is on stand-by the clock speed goes down drastically in order to save battery when the phone is on stand-by, and most of the system processes have to be brought back from suspension.

Yeah, there is new info. SGS3 has it too. Which means: Tough luck trying to get it fixed on SGS2, when even the successor has the same problem.

AFAIK it's ICS related
I saw (in Siyah thread if I'm right) that the kernel is a half second longer to be restored (I don't know if its the right word) than in GB after deep sleep
Phone : Galaxy S II
Kernel : Dorimanx
Rom : Disaster ROM By Mirko DDD - 4.1.2 or RootBox nightly

Tablets : Archos 101 it - Galaxy Tab 2 10.1
CYANOBIZ - 4.0.4 - Stock - 4.1.2

On Samsung devices with GB, it takes 600ms to wake the phone up, on ICS, it takes 1000ms.

However, this is not ICS's fault. HTC devices like Sensation or One X wake up instantly even on ICS. This delay happens only on Samsung phones. Shame on you Samsung!

Here is a cheap and simple and most importantly a reliable way to fix this issue.

The text explanation...

Buy the official extended battery. Its very cheap, got mine for 30 aud.

Install the terminal emulator app. It places an icon notification and thus is the only app that doesn't keep getting killed in the background and consequently stops helping with the wake up lag.
Side effect... you also know if ur phone reboots hot or cold, u get some insight on your stability.

The graphical explanation...

Below are some screens on my setup. I use AOKP and Fluxxi kernel.
