Q: Does Yosemite Improve or Reduce Performance?

Hi there,

 

I'm a user of a Macbook Pro 15 Retina from 2013, and I'm considering upgrading to Yosemite. Although I do want to upgrade for the new look and features, I do have one major reservation. If Yosemite is going to make my computer less responsive, laggy ect. then I'm going to hugely regret the decision. For me Mavericks is a great OS, and so a performance hit would seriously put me off. Can anyone share some experience they've had with the full version please?

 

Any and all feedback is greatly appreciated!

    Luckily, most of their advice was removed by the hosts due to breaking the Terms Of Use which was yet another area the poster failed to comprehend. Which is lucky for any serious posters who will come to this post at some later date.

    I have started working my way through the list of "offenders" Western Digital had a look at the results of running "top" and have concluded that the utility program they provide is not hogging memory.  According to "top" the offenders are:

     

    com.apple.We - 40Mb - not sure what this is but looks vital

    cloudphotosd - 12Mb

    WDDriveUtility - 2124kb (as above)

    com.apple.We - 32Mb - as above

    Dropbox - 43Mb

    rapportd - 54Mb - my bank security software

    CVMCompiler - 17Mb - ??

    imagent - 47Mb - not sure what this is either.

     

    I would attach the "top" dump with their red marks but there doesn't seem to be a way of doing this.  None of the figures are big in comparison to the memory available.  As to CPU time used the largest users are Dropbox which is essential software and rapportd ditto.  Both use a staggering 0.4% of CPU time!

     

    Still waiting for Seagate to get back to me on their uninstall methods.

    1. It is not about "hogging memory". The WD or Seagate softwares are designed to work in a Windows environment, but also available for Mac. These softwares are maybe helpful in the Windows environment for accessing and timing the disks, but in a OSX environment they are counterproductive.

    2. The memory handling in Yosemite is such that Yosemite collects all the memory "under its arm" to speedily allocate to the different apps that need it, at the moment that they need it, not before and not after: you can see this as a sort of time compression. Much more efficient than older OSX and Windows, although also Mavericks already did a big step in this direction.

    It seems that Yosemite hogs all memory but it does not, but makes allocation much more efficient and faster.

    Thus, as long as you do not have much to much Ram installed, you will see practically no "free" memory.

    As TerenceDevlin already explained shortly. And poster Zanaelf just does not understand any of it and from that makes idiotic comments.
