holygamer Posted January 14, 2012 Posted January 14, 2012 (edited) I have: Vista 32 Bit Athlon 64 X2 Dual Core 3800+ (2GHz) 4 GB Ram ImgBurn works fine when I'm not doing anything else and I can get the full 4x on my Blurays. However if I do any CPU intensive task (if that's the correct term) such as performing noise reduction on an audio file or when I mux a file with TS Muxer the speed drops to any number below 4x and can drop to 0. It just seems to be random what speed it decides to give me. I performed noise reduction on a file which takes several minutes. The first few minutes the speed dropped between 2-0. The last few minutes the speed went up to 4x again! If it drops to 0 it says "Waiting for hard disk activity to reach threshold level Current 1,300, Target: 1,000". The current number jumps between 1,000 and 2,000 every split second. The speed is always above 1,000 so why does it say that? I'm burning from an image on my USB 2.0 drive and there's nothing else that's using the drive so why does it say that? I notice as well that before I get the above message, the buffer constantly empties and fills back up and it says "Waiting for buffers to recover" When Muxing a file and burning at the same time - on Task Manager my CPU usage doesn't go above 50% and the memory used is below 3GB. I got 3.5x then when the muxing was at about 60% complete I got 0x - it just seems to be random. When editing an audio file the CPU usage is between 95%-100% but it doesn't slow my PC down and I can still do other stuff such as browse the web without problem. I have a dual core so I didn't think performing 2 tasks such as editing an audio file and burning at the same time would be a problem. I'm sure I read an article somewhere that said you don't need much power to burn a disc these days and you can multitask without problems. ImBurn is only taking up about 50K of memory. Can anyone shed some light on all of this? Do I need a quad-core to get full speed when multi-tasking? Here's a log from one of those sessions. I 04:25:07 Operation Started!

Cynthia Posted January 14, 2012 Posted January 14, 2012 How much hard disk reading/writing is that sound mixing using? CPU is not the issue here, looks more as the hard disk is "occupied".
holygamer Posted January 15, 2012 Author Posted January 15, 2012 How much hard disk reading/writing is that sound mixing using? CPU is not the issue here, looks more as the hard disk is "occupied". Can you please tell me specifically where I should go to find that information? The sound editing has the disk cache on my internal hard drive. The disc being burned is read from an ISO on my USB 2.0 drive. So they's both using a different hard drive so I don't understand why I'm getting this "occupied message".
LIGHTNING UK! Posted January 15, 2012 Posted January 15, 2012 USB uses CPU cycles. If you're fully utilising your CPU (both cores by the sounds of it) with your sound editing then there won't be as much to go round and you'll get delays in the USB comms and it'll kill the transfer speed. It's taking about 6 seconds to read 40 MB from the drive and refill the buffer... but then it's only taking just over 2 seconds to write that 40 MB to the Blu-ray disc. Perhaps you'd have more luck if you limited your sound editing program to just using a single core.
