Lagging on my 13" rMBP.

I'm around the same usage as you and when I go to activity monitor it says I'm using 6.5 GB is that where you are?
----------
Should i have more than 6.5 GB memory free on my 8GB rMBP? What's ideal?
----------
I'm also closing out all applications and programs as I am finished using them. Are there any other things I can do to clear up space or is the 6.5 GB I'm using pretty much standard?
I read this thread, but went ahead and got my 13" rMBP. I did see some lag on the display model and on mine, but usually only in scaled modes. Specifially the 1680X1050 mode, because it has to render at 3360x2100! That's a lot of pixels for any integrated card.
On the normal 1280x800 HiDPI mode, it's perfectly fine. And if I use my external monitor exclusively, it's even faster (1080p).
I'd say it's a non issue with the Iris for the most part. The HD4000 model had some issues for sure though. To each his own
Screenshots of my currently running stuff. Zero lag.

Right now I'm running WoW, Spotify, 4 Safari tabs, and iMessage and Activity monitor is showing "Memory Used 7.99GB" but I'm not having any noticeable lag.
FWIW I play WoW on 1440x900 on high graphics (shadows, water, ssao either off or low for those settings), not sure if that has any bearing.
Don't own a rMBP, however the OPs lag even impacted Intel IGP Mac minis until the recent update to Mavericks. In my opinion I'd be leaning towards Apple is still bug fixing the memory management with Core i-series systems, UI/system lag has been hitting some Macs harder than others...
Mavericks runs like crap on my 15" 2012 MBP(when Intel IGP is active), oddly its snappy on a 2010 13" MBP with half the RAM... a friends 2011 Mac mini was snail like w/30" monitor

Just got my new base Late 2013 rMBP today. From what i can tell, I only see noticeable lag(although its very slight) when running in 1680x1050 or 1920x1200 mode. With the "best for retina" setting, everything is smoother than silk.
I must say that I'm impressed by the Iris Pro overall.

Mavericks uses available memory. It doesn't mean it isn't available. The most important thing is your memory pressure. If it is green you are good. I used the 8GB model for a bit and even with nothing open it was consuming over 6GB of ram. It's perfectly normal.
I cannot speak for all, but mine has never shown any lag and doesn't feel any different than my 2014 MBA. I usually run it at best for retina which emulates 1280x800. Sometimes I run it at 1440x900 and have never had any lag on that either.
Thank you. I shall have another play with them in the apple store and probably buy a BTO before the back-to-school offer runs out.
I find this lag is increased on Haswell based machines. From what I can tell, it is an issue with there being a lag time between the GPU going from a low power to higher power state.
When you are just using software normally there really isn't much strain on the GPU, so the OS will clock it down to reduce power consumption and heat. Then when you try to re-size a window or open mission control etc it will lag for a second while the chip is still in this low power state, as the animation wont be delayed until the chip clocks back up.
Once the OS realizes it needs more power, the chip will clock up and the lag will mostly go away, until you allow the system to settle again. I see this all the time when scrolling image heavy web pages or switching from space to space. Laggy at first, then nice and smooth until I let the system idle for a second on a static scene.
Of course, the higher you set your resolution, the more strain will be put on the GPU which will of course increase the lag.
The issue is exacerbated by retina screens as any resolution beyond "best for retina" will start rendering your screen at significantly higher resolutions than the screen itself. For example a HiDPI "1920x1200" setting on a 15" rMBP will render the whole screen at 3840x2400 and scale the resulting image down to your native resolution. This is almost 2x the resolution over a HiDPI "best for retina" 2880x1800 (1440x900 equivalent working space).
5.1 Million pixels vs 9.2 million.
One thing you can do is use applets like "RDM" to set your resoltion to a non HiDPI one. If you want the working space of 1680x1050, but don't like the additional lag the HiDPI version introduces, you can set it to actually run at 1680x1050. Because of the small physical size of the screen the resulting image will still look pretty decent, but will be significantly less taxing on the system.
Cheers.

This is what I've suspected for a long time now. I usually only see lag when activating Mission Control for the first time in a while, then if I were to keep activating and dismissing Mission Control, no lag would be evident. I've only ever noticed this on portable machines, it doesn't happen on my late 2013 27" iMac but does on my late 2013 15" rMBP - entering a lower power state to save battery is probably the cause.
