Jesus... 1gb kernel task after restart...

[blow45]

On a 2.3ghz 2011 mac mini...

Even for lion's standards (generally very low) this is atrocious...

What on earth is happening?

fiy: I killed simbl, restarted without it and it's still the same s... state

Try sorting by CPU in descending order (highest values on top) and post another screen shot.

Did you notice this after you recently upgraded to 16GB?

 

[blow45]

yup? Do you have any insight as to why this might be happening? Why would kernel task double itself over a ram upgrade?

enter this command in the terminal:

kextstat | grep -v com.apple

It shows what 3rd party kernel extensions are installed.

The kernel has to keep track of memory pages. It's only expected that it grows in size when you increase the amount of memory available to your system.

yeah but to 1.1gb?

On my machine with 8GB RAM kernel_task starts out around 500MB, quickly goes to 700MB just using Safari and Mail, and after a days work sits around 1GB. I only have Air Display's kexts loaded. So, I'm guessing what you're seeing is normal with 16GB RAM.

Did the kext command show any 3rd party extensions that could be contributing?

It's my office mac, I ll check it tomorrow.

I don't know specifically, but the gist is that Lion takes more if you have more. The same thing happened to me when I installed 16GB RAM.
