Only utilizing 4/8 Cores with Retina MacBook Pro

Post by Claudio » Tue Aug 21, 2012 4:53 pm

As the bars show in Activity Monitor under 10.8 using the new Retina MacBook Pro, only 4 of the 8 available hyper threaded cores are be utilized (running no other applications at the time). Will a future release utilize all 8 processors?

MakeMKV doesn't re-encode the video. With a setup like yours, the CPU is hardly a bottleneck.

I should of been more specific. This is when I'm using MakeMKV with a BDMV folder on my internal SSD, not from an external USB 2.0 Blu-Ray drive. The SSD has given speeds of 450MBps Read/400MBps Write, so couldn't the use of 8 cores be beneficial?

Depends. How quickly (or not) is it going (i.e. how long does it take to convert a BDMV to one or more MKVs)?

extremely quick, maybe only a minute or so.

That kind of speed sounds perfectly normal for that kind of setup, IMO (i.e. not too slow or anything). It juts seems like the CPU is not a bottleneck, even with such a fast drive.
