Sef:

I'm in PAL and my TL for 100 secs of video, is 2500 frames. They were exported to ISO in 4'10" That is almost the same speed.  My CPU is 2.4 gHz and a double core.

Maybe a defrag of the render disk could improve the speed.

Facit: long timelines require long ISO producing times.

But then, the problem for overheating is a seriouis one. Lucky, my system has no problems with this.

Thanks for that data.  Was that an HDV project?

(BTW: I cut a hole in the side of my computer case and installed another fan.  Maybe will help with heat.  I wonder whether reseating the zeon heat sinks with better conducting medium might be needed, but I'm afraid to mess with it, and the custom builders who made the computer supposedly knew what they were doing.  I'll see how it goes next time it renders at 100% (only certain cases).  Winter less of a problem with lower room temperature.)

Yes, see here.

 Yes -- our speeds are not too different if you adjust 2500 frames of 50i against 3000 frames of 60i -- although you are still getting a little more performance out of your dual core 2.4 Ghz than I am from my dual processor 2.8 GHz.  I'd like to identify what tweak I'm missing if any -- maybe dual cores are just more integrated and better technology than separate processors.  Somehow I don't think fragmentation is the problem because I would think the drive cache can buffer the writes, and also because file copying goes so much faster than "rendering" an iso file -- makes me think it is "computation bound", not "io bound", performance-wise.

did you try to defrag your Render and Media drives?

Are they different (really different, I mean: separate drives)?

I did not, but will give it a try, and I'll re-time it before and after defrag.  My render drive is getting full and pretty messy.

My "media" drive is definitely separate from the render drive (source media is on brand new terrabyte drive, practically empty), but here is the rub: because I color-corrected the whole timeline, the "source" for the iso process is now essentially on the render drive.

I made the destination of the iso file back on the source drive to try to keep reads and writes separate during dvd iso building.  But here's the other rub: the iso-making process seems to make temporary files first on the render drive -- so it is actually reading and writing to the same drive I think!

So here is a new question: how do we configure LE to make the "edit render process" go to one drive and the "dvd iso process" temporary files go to a different drive?

You can use your new "Media" drive for rendering also.  It will not interfere with media streams when either importing or exporting.  I like to keep my render files on a separate drive, but functionally it is not required.  This would let you continue working until you have a chance to sort out your "messy" render drive.
