    Question Same model Macbook Air faster than the other?
    My father just received his 13" Macbook Air 2012 i5 with 8 GB of RAM yesterday. I have the same exact model, but for some reason his machine feels "slightly" slower than mine. Is this possible? Or are we both just dead wrong about this.

    2012 13" MBP (2.5 i5, 8GB)
    If it's "slightly" slower, I'm going to guess that your observations are purely subjective. No two machines, regardless of specs, are going to perform in exactly the same way.

    It all depends:

    - It depends on what software is installed and used.
    - If there are any apps. that load upon startup
    - If EXACTLY the same things are performed in each computer to logically & scientifically state that one computer is faster than another.
    - and there are other things such as...cache files, permissions, swap files sizes, amount of page-outs, etc. that can affect things (since no two computers are used exactly the same)

    Also...DO NOT make this sort of judgement based on doing things via the internet. Internet speeds can & do vary...so if one of these MBA's are being used during a "fast" internet period...and the other during a "slower" internet period...then they will "seem" different.

    And just for completeness. The only accurate way to test the speed of two computers is to use a benchmarking program...or have both computers sitting side by side...both setup the same way (specifications)...and both doing EXACTLY the same tasks at the same time. Then using a stopwatch (or possibly visually if the speed difference is that great).

    Also...no two computers (even the exact same model & configuration) are EXACTLY the same speed. There will always be very small differences (but this is really more of a technical point than real world).

    Thank you for the quick responses!

    His laptop is not currently home right now, but one of the main differences we noticed was the scrolling on webpages. My scrolling seems to be a lot smoother when navigating the same exact web page.

    Use a known speed test like Black Magic Disk Speed Test to compare them and let us know how they compare.

    They are both averaging about 230 write / 440 read. Is that about normal?

    if you click apple menu > about this mac > more info > system report > serial ATA > Link speed is 6 gigabit
    then your write speed should be more, so does read speed.
    because my core 2 speed is about 200 (write) and 260 (read), mine is SATA 2 ssd.

    It reads Link Speed: 6gb. You are saying my speeds should be higher than 230 and 440?
