Yet more CCE/Avisynth speed probs

[greengolem]

I am having a baffling (to me) CCE speed problem. I've go two machines running Win2k pro (please don't laugh at my configs; I'm really broke right now):


Desktop:
AMD Athlon 1100
128 MB RAM
HD: WD200BB (Western Digital 20G Caviar)
7,200 RPM
2 MB Buffer
Buffer To Disk 400 Mbits/s (Max)
Read Seek Time (Average) 8.9 ms
Write Seek Time (Average) 10.9 ms
Mode 5 Ultra ATA 100 MB/s
(And yes, BIOS reports that we're running mode 5)
Windows 2000 sp3


Laptop:
Intel PIII 850
128 MB RAM
HD: IC25N020ATCS04-0 (IBM Travelstar 20GN)
4,200 RPM
2 MB Buffer
Buffer To Disk 203 Mbits/s (Max)
Read Seek Time (Average) 12 ms
Write Seek Time (Average) 13 ms
Mode 4 Ultra ATA 66 MB/s
Windows 2000 sp3


Ok, so you can see the disk on the laptop is (supposedly) a little slower, and there is the difference in CPUs.

Here's the issue: using Avisynth/mpeg2dec/CCE 2.50 on both machines, on the same VOBs, same D2V project (all files local), etc, the desktop can barely make 0.2x on CCE encoding, and the laptop gets 0.795x (which is perfectly acceptable for my purposes).

(FYI, my purpose is a DVD-9 to DVD-5 backup, so this is all using the first CCE pass in the Robshot method. And I'm working on Disney's Atlantis, a 3-PGC main movie.)

What the hell am I missing?!? I know I'm low on memory, but BOTH machines have 128 MB! And they both have the standard Win3k 195-384MB cache on the same disk as I'm using for reading/encoding (I know, I know). What could account for the huge difference?

I've reinstalled the desktop from scratch, triple-checked the HD ATA speeds, and made sure that I'm not running any non-essential processes/services.

I would be very happy to supply any additional specs for the two machines, but there has got to just be something wrong with the desktop, right? I mean, it can't be THAT slow, can it?

First I would open up the vob(s) with dvd2avi and preview them to
compare what fps you are getting on both machines.

Then open up both avs files from VirtualDub and compare viewing
speeds.

This might give you some insight as to were the bottle neck is.

Fixed this by turning down hardware acceleration in video advanced properties several notches.

For anyone who might be experiencing the same problem, I have an Nvidia TNT2 Model 64, w/ 32MB RAM. I am using their drivers for Win2k, v6.13.10.3082, and MS DirectX 8.1. In the Display control panel, under the Settings tab, I clicked Advanced. In the Advanced properties window, under the Troubleshooting tab, I reduced the hardware acceleration to the third tick.

Just doing this increased my CCE transcode speed by a factor of 6 or 7. But it was severly impeded before this.

I'm getting 1.35 using AVISynth and CCE 2.64, I'll have to try that video accelerator setting and see if it changes anything.

Using P4 2.0Ghz with Geforce3 and 3 7200 RPM drives.
