does your rMBP13 have >1GB kernel since 10.8.3?

Since the update last week, my kernel_task now takes up at least 1.2GB of RAM, which is a huge increase from the 6/700MB it used to be. I'm wondering if this is specific to my machine, or are other retina owners seeing similar?

The only extensions that have been updated which might explain it are shown here:

Same here (Mac Mini 2012) and others as well, you're not the only one.

Always wondered what the kernel task is doing, let alone hogging up 1.4 gig (in my case)

I guess they are doing more aggressive caching now. Despite the higher kernel RAM utilisation, I still have no pageouts and the system feels snappier overall (this is on a 15" rMBP).

Ya no pageouts really here unless i start parallels and work heavy with the VM.

My Retina is using over 2GB at first boot-up with nothing loaded. Always has.

For some reason, my usage seems to cause page outs more often lately...

But there is no adverse effect on performance (no lag, stutter), and I probably wouldn't have noticed it had it not been for Activity Monitor.

Wow - that's high, how long was your up-time at that point, what had you been running?

Same here! Non Retina 2012 Model though. I tried rebooting but no luck.

1.41GB for me. WTF?

I didn't check this before the 10.8.3 update so I don't know what it was previously.

Have you started using some new software lately? If I am not mistaken, accessing memory-mapped files will also show up as page misses, even though they are often designed to work this way.

My kernel has been over 1 GB since the update--currently 1.33--but it seems to me that some tasks have been reallocated as many of the other processes--like webprocess take up less RAM. Can't say I am using less RAM but I really don't see me using any more total RAM after the update. Doing my normal tasks and currently have 2.76 Free and 906 Inactive (out of 8GB). So in the end, all is good.

I took that screenshot about the time I made the post. And current uptime says 2 days 19 hours... so I'd guess about 2.5 days.

I'd just been running the usual: Safari + Mail + Xcode + Skype + Photoshop + probably Preview as I had to look at some PDFs.

You can probably tell from the screenshot, but I already closed the heavy hitters (Xcode and Photoshop) by that time.

And Photoshop was open to edit a 1024 x 768 transparent PNG. Hardly something that would cause a multi-GB RAM usage spike.

Nope, nothing new. I haven't installed anything new on this computer for 2 months now.
