Multiple cores make a big difference

I recently upgraded to a quad core PC & it sure is a lot faster processing video than the old single core machine.

I use to start the authoring process & then go eat dinner or watch TV because a 2 hour video took about an hour to author. I just authored a video which had two 55 minute projects with titles & menu. It took just under 5 minutes, & that included the "calculating" time.

Anyway I'm really impressed with what an upgraded PC can do.

Big difference could also be due to the type of video you started with.
And of course, the speed of the hard drive(s) plays an important part, as well.

Wonder what computer you had before? :)

I had a 2.6GHz P4 and now have an AMD 3.0GHz quad core. The new one has a 7200 rpm HDD, but IIRC so did the old one. Of course memory & bus speeds are faster on the new system. But the speed difference is incredible when working with VRD.

I'll take some flack for this, but ...
an old single-core P4 is a bit of a dog.

A core2duo with reasonable cache, or any modern AMD (even my old two-cpu Opteron server), can be a significant boost.
Even so, I can't explain your throughput improvement.
Were you reading files off an external USB drive before? :)

Oh, and for best performance you should probably read from one fast drive, and write to a second.
Not sure how valuable that is any more, with such a heavier CPU-load from processing HD videos...

With the P4 I initially read & wrote to the same internal HDD. Then I changed to reading from a USB drive & writing to the internal HDD. But I don't think it made much difference either way.

With the quad core I have been reading & writing to the same internal HDD. It's just so fast that I have not tried a USB drive. But I'll give that a try & see if there is any speed difference.

Just for a point of reference on how slow the P4 was, my Internet browsing is faster with the quad core. Pages actually display faster. IOW the 3 Mbps DSL Internet connection was not the weakest link, the old PC was.

I didn't mean to suggest USB drives are fast.
For best performance, you want internal SATA drives.

But some years ago, one of the members reorganized their computer system, and plugged their USB drive into a front connector instead of one in the back of their computer.
About the same time, their VRD performance took a hit.
Turned out, the connectors on the back were USB 2, and on the front, slow USB 1. ;)

When I had the old P4 somewhere it was suggested I try using a second drive in order to speed up the process. I don't recall if it actually mentioned internal or USB, but I had a USB 2 so that is what I tried.

Now I have a USB 3 drive & port. I don't know if that will help or hurt, but I'll try it on my next project.
