Honestly, that's not unusual for your laptop specs. Ultra Key and Lumetri are incredibly CPU intensive. Are you also doing an Advanced Spill Suppresion and Key Cleaner? You only have a Sandy Bridge Core i7 2720QM I'm assuming, based on a quick search I did for 2011 MacBook Pro specs. That's a 7 year old processor. I'm assuming you have discrete graphics via an AMD Radeon HD 6750M built into that as well. Do you have the option available to use your GPU to help render at least? If ME supports OpenCL on that card, it may help a bit. I believe some of those effects are GPU accelerated, but someone would have to confirm that as I'm not sure. I've done green screen renders with Ultra Key, Adv Spill Suppressor, Key Cleaner, and a little bit of Lumetri with a Sandy Bridge-E Core i7-3820, 32GB RAM, with a 4GB nVidia GTX 960 and with an hour of footage, it took 13 hours. That's basically a 2012 spec system and it's a desktop, so it's going to perform better, but 13 hours is still a decent amount of time. Your results are rather normal. It's just a lot for the CPU to handle. Bill Kearney LightShiftVideo.com
