Well for benchmarking you can download GeekBench or check out the benchmark scores for Macs. My story: I still have my i5-2.5Ghz Macbook MD313 (2011) and I upgraded to 2x 240gb 560mbps SSD in RAID 1 which get speeds up to 800mbps. Then I upgraded my RAM to 16gb. It only has 512mb integrated HD3000 GPU and this 2011 machine outruns my 2013 i5-3.2Ghz 27" iMac ...

Intel Core i5 is a significantly more powerful processor than Intel Core m3. I can't say for sure that it strictly won't work, but it will likely not be very smooth performance at all, unless perhaps you turn all the settings down to their minimum. I've heard even on MacBook Pro's without dedicated graphics (just intel HD) Simcity 5 performance is poor (lots ...

I recommend enabling trim and doing firmware updates! :)

Moscarda, friend: These are good points, each, and I agree with your conclusion that the list of system daemons or services which are running after the operating system installation is rather excessive. Between performance and ease-of-operation I readily prefer performance. Thus, I tend to reduce to bare minimum the list of services which are allowed to ...

When you run the command sysctl hw.cpufrequency you are getting a contestant that was given to the OS at startup. If you want to get the CPU frequency "on-the-fly" you will need to poll the CPU. That's what the Intel Power Gadget is doing. As for why you are not seeing a performance increase with your specific application, it could be from any number of ...

symptomsd runs as part of the CrashReportor framework.

As noted by Apple here: Activity Monitor may show that a process named kernel_task is using a large percentage of your CPU, and during this time you may notice a lot of fan activity. This process helps manage temperature by making the CPU less available to processes that are using the CPU intensely. In other words, kernel_task responds to conditions that ...

Barring magic the only solution of load time should be to load an app in the background (completely or in part), so that it can load faster when called up by the user. Obviously application developers can work on their app to make it load faster (like Libreoffice did) but this seems to be a completely different story. Preloading apps obviously has the ...

My experience supports the theory that excessive CPU usage causes kernel_task to run high. In my case, it often happens when I have too many browser windows open or YouTube videos playing. Closing windows or apps usually solves the problem. Other ways to cool things down: Higher fan speed. I use Macs Fan Control from CrystalIdea to manually raise my ...

Time Machine and OS X is tuned to throttle the IO and possibly the CPU usage of the backup task. You can do a few things to modify that behavior - but from the speed benchmark and my experience - a 12 to 48 hour initial backup is not abnormal or indicative of slow backups once you have a few intervals backed up. You could log out and minimize other apps / ...

The speed you see there is not unusual. I have seen various USB3 external harddrives vary from about 60 MB/s to about 120 MB/s. These speeds can be expected from ordinary hard drives - you'll to buy an SSD to get much higher speeds. However please keep in mind that these speeds are the bulk transfer speed. I.e. if you transfer only one large file without ...

The first backup will always take a long time. Possibly even overnight. Then it gets faster because it backups only modified files. I had the same speed with an Airport Time Capsule.
