Painfully slow encoding with i7 970

Just picked up a new cpu from the MM and am getting some terrible encoding performance out of it.

Settings in Handbrake, are constant 10,000kbps with audio passthru and same resolution as the original (mkv made from the bluray disc)

Do I have some settings wrong? it doesn't even seem to using 100% cpu, infact only about 50% on each core is getting involved!
 
Maybe the drive it's on is choking? You're reading from it and writing to it at the same time.

Is the drive read speed fast? Check if it's reading near it's max read speed. Could be the drive hampering it if it isn't.

Could be going slower because it's doing a 2 pass encode?
 
It's a Samsung F3 which is about a year old, it should be fine.
I think you may be right with the 2 pass encoding theory, on 1 pass it goes at about 50fps, that extra pass really gives it a hit! Is it even worth it?

Depends, it's trying it's best to encode the video into whatever settings you have set (on the 2nd pass)

Usually the a 1 pass will try it's best to fit the video into the settings required but if it can't obviously quality will suffer.

Try a test and encode it with one pass 10Mbps. The quality wont really be that much lower, unless you are trying to store it at the best/nearest quality to the original. However you already have the Bluray so it doesn't matter as you have the source.
 
well it all depends your bitrate and 2 pass encoding, usually the 2nd pass takes 3-4 times longer than the first pass, as you are ensuring a better quality encode, try without 2 pass and see if you can tell the difference, also maybe try a different programme maybe, i use a free one called vidcoder wich looks very similar to what you are using and it actually uses handbrake to do the encoding, but it does almost max out my cpu,

omg i just noticed how long its been running, really shouldnt take that long m8.
