conversion speed / execution time

[g'ner]

Hi I just built a new win7 media box and last night I converted a dvd iso to individual episode mkv files and I noticed that both my new box and old box took about the same time to convert the similar tasks (dvds iso to mkv files). Shouldn't the new box be x times faster. Is the the conversion time throttled by the sw? How can I speed this up?

Old Box spec
win xp
pentium 3 1.5ghz single core
758 megs of ram
media on a 1tb drive esata through a pci card (1.5sata?)
used 100% of resources took convert ~10min execution time

New Box
win7 64bit
AMD|ATH II X2 250 AM3 3.0ghz dual core
4gigs of ram
media on 1tb esata through on board esata (1.5sata?)
low percentage of resources ~20 to 25% of resources took ~10min execution time

I think it's actually due to the speed of your bluray drive. Please post here your findings so we can keep everything together.

everything was an iso (image), so no rom(bl/dvd) was a factor. I am seeing better performance tonight thou, around 5-7 min. It must just depend on the iso. I am also starting to think disk write speed is the common bottle neck.

Hi!

Add a second physical hard drive and read from one drive and write to the other for a drastic reduction in time required...

I second that. Instead of adding internal drives I added a USB 3.0 dual port card and USB Superspeed docking stations. 6 Gb/sec internal drives stuck in the docks operate at full speed. Muxing flies.

I prefer ESATA. Not sure what the performance penalty is with HDs but with a BR drive I saw 10-15% loss with USB, no performance loss with ESATA.

You must be talking USB 2.0. I get sequential read from WD 6 Gb/sec 1 TB HD in USB 3.0 dock at 143 MB/sec Crystal Diskmark. The muxing doesn't slow me down.

I know this thread was last updated some time ago but I just wanted to understand the main pinch point for performance.

MakeMKV certainly seems pretty fast. Processing a folder structure that had been ripped by AnyDVD; CPU and memory didn't seem to be the bottle neck so I can only assume that disk IO is the main rate determing factor? For ultimate performance reading from an SSD disk and writing to an SSD disk which result in ultimate performance rather than improvement to any other component?
