PROBLEM SHORT: When running multiple occurences of clonedvd simultaneously processing 2 movies at once - my system I/O drops by a power of 10X and the time to process two disks nearly triples. - take it to 3x and performance isn't worth discussing.
DETAIL:
Running Win 2k pro - clonedvd (latest) and anydvd (latest)
2K version 5.0.2195 SP2 2195
motherboard onboard 4X 32bit ATA 33/66/100/133
AMD 1.2ghz 1 CPU
100mhz front side bus
756 mb ram - average of 4-500MB free during all processing when monitored.
total virtual memory 2.3GB
avail VM - 1.8GB
F is IBM ata100 - E is maxtor ata133
I'm normally a unix freak so this problem is for the windows gurus cuz frankly - I just can't find the info anywhere on how to correct or improve this. I've looked.
This is very likely nothing to do with cloneDVD which is a superior product overall.
I run cloneDVD and process a MOVIE (any movie) as input from disk F: and I use a seperate disk and IDE channel as cache for the output files E: - then the final product is written to D: Pioneer DVR-108
I pull up performance and check the read bytes/sec and write bytes/sec. Over 20MB/sec - bursting 22-30MB/sec. seems appropriate and I have a DVD in 20 minutes written at 8x.
I think why not process two movies at once?
So I run 2 occurences of clonedvd at the same time - processing 2 movies from F: - using E: as cache for both and outputing to D: and G: both DVR-108.
you would expect some decrease of I/O but total net I/O should be close since I'm doing only READING from F and WRITING to E: this should keep from hammering the drives too much.
wrong.
My average I/O in performance drops to 1.8MB/sec and the processing time for the set inceases to 1 hour.
If I run 3 at a time - disk I/O drops to under 1MB/sec and the time to produce a single dvd5 is 3 hours - 900% increase.
As a comparison - I ran eight simultaneous occurences of DVD2OneX on Mac OS X (unix) and for lack of hard disks - simply used / <root> as input and output. The disk naturally was thrashed a bit - but so what - I compressed over 90GB of movies to 32GB appx. in 2.5 hours and cut 8 dvd's.
That's pretty normal scaling when you figure it takes 20 minutes to do a single compress.
did I miss something or is windows missing something.
hardly a newbie - but we live in a society of labels
this one is mine for now
I now leave you in the same bewildered
self-inflicted state of confusion I found you in.
