PT Performance - Davec I & Davec II Tests

[JPS]

New Intel system:

Asus P4C800 Deluxe (Intel 875 chipset)
Intel P4 2.8ghz/(800fsb) CPU
1024 MB Corsair XMS 3200 DDR (2x512)
WD Raptor SATA 36 G (OS drive)
WD 80 G IDE /8MB buffer (Audio Drive)
XP Home Edition
Antec 430 True Power PS

32 tracks + 12 aux @128 buffer (44.1/24)

If the drives are reversed, and the SATA Raptor drive is used as the audio drive and the WD 80 G IDE drive is used for the OS, then I receive the following results:

32 tracks + 14 aux @128 buffer (44.1/23)

If "write catching" is disabled on the SATA drive, then I am able to add another 4 tracks, although it's painfully slow on the last two:

32 tracks + 18 aux @ 128 (write catching disabled)


Upgraded AMD system:

Asus A7N266-VM/AA (original nForce chipset)
AMD 2400+(266fsb) CPU
512 MB Crutial 2100 DDR (2x256)
WD 40 G HD (OS drive)
WD 40 G HD (Audio drive)
XP Home Edition
Enermax 365w Whisper PS

32 tracks + 2 aux @ 128 buffer (44.1/24)
32 tracks + 8 aux @ 2048 buffer (44.1/24)

<font size="2" face="Verdana, Arial">It would be interesting to see the result using the "WD Raptor SATA 36 GB" as the audio drive, is that the 10000 RPM drive?, just a thought, I wouldn't expect you to swap your drives and reinstall your OS just for this...lol

I have re-tuned the Athlon XP system with new drivers/bios and disabled my onboard sound card and got 32+11, previously was 32+5 (digi002).

Haigbabe, I have the Digi 001.

Booyah, I also am curious and thinking about swapping drives. I have a copy of Ghost. So, I should be able to put a drive image copy on the IDE drive. Just don't know if it will boot OK? Anybody have experience in this with XP? If so, all I have to do is go into the Bios and change the IDE drive to the boot drive and I will be up and running. Then I can easily use the Raptor for audio. Just not sure how XP will respond to this maneuver.

[Booyah]

XP responds to this nicely so long as your SATA drivers are installed and working, its all about the bios boot sequence.

Using the SATA drive for audio (instead of OS)in my setup looks to improve performance by 2 tracks. I went back and edited my original post.

<font size="2" face="Verdana, Arial">Slight improvement, you could try 1024 buffer and drop your display to 8-bit color or lower the acceleration for display and might get more, thanks for testing this [img]images/icons/smile.gif[/img] , maybe 6 mo's from now they will have larger capacity SATA drives and I will try one then with a addon Promise SATA card.

Nice system you got there!.

In a totally shameless effort to get a few more tracks, I used minimoog's trick- disable "write catching." And it worked pretty good. Got another 4 tracks, but it was so slow at 32 + 18 that the counter updated only 4 times in the 60 second test: at 31 sec, 43 sec, 57sec and 1 min 11 sec. I could hardly believe it could keep going. I finally stopped it after 2 minutes. I re-edited my original post with minimoog's "enhancement" and added this result.

I then tried 32 + 19 and got the error message "Running out of CPU and Stop tormenting your computer!"

On my drive disabling write catching slows down the write speed from 45 MB/s to 7 MB/s and reduces CPU usage from 10-12% to 2%. I used the Norton Performance Disk test to get this info.

Just set up the new Studio-Beast. This is the straight out of the box test the only tweak was setting the CPU usage to 85%.

Here's the beast:

PT 5.3.1 - Digi001
Win XP Home
MOBO - ASUS A7V8X-X
CPU - Athlon XP 2700+
RAM - 1 GB Micron
Drives - 1 WD 60GB 7200 RPM HD - two partitions

Tracks - 32+14
Buffer - 1024

Pretty happy with the performance so far. I have a second IDE 7200 HD that I'm going to use for the wavs. Not sure how much of a difference it'll make. [img]images/icons/cool.gif[/img]

<font size="2" face="Verdana, Arial">Oh it will make a difference in performance here. Two partition systems actually run slower than a one partition system if you have the system on one partition and the audio on the other.
Way to go here on the new system though.

Just upgraded my computer yesterday. Here are my results. I'm pretty happy with what I got I guess. I think it's probably plenty adequate for what I need. I haven't done any XP tweaks or anything.

MOBO: Intel D845GEBV2
