CPU usage between tracks
« on: March 20, 2004, 05:56:34 pm »

Ive noticed within the 10.0 builds that between tracks and even in long silences during tracks, my computer slows to a crawl and the CPU usage skyrockets.
Has this been touched on before  ?

Do you have the Do not play silence option enabled (under Options > Playback)?  If so, don't do that.

Nope. I never had it enabled.

Does turning DSP (equalizer, etc.) on or off make a difference?

Are your files on a slow source?

With a 1.8 Ghz, you should be able to play fullscreen games with MC cranking in the background and not know the difference.

The problem is that some CPU's get really slow when dealing with numbers close to 0, which can happen when a bunch of silence is passed through the DSP chain.

If you can isolate what DSP effect / equalizer does it, we may be able to work around it.

Thanks.

Hi Built;

One thing that I noticed is that you seem to have too little memory on your Win XP system.

The screen you provide shows only 260MB total (I assume you have a 256MB) which is totally inadequate for Win XP.

Yes, 256MB does allow you to run XP, but just barely.  512MB is generally considered to be the "Sweet Spot" for XP & allows all programs to run more freely with less processor usage & less swap file usage which can really slow things down a lot.

Many systems today come with 1GB of memory.

I was running 512MB on my XP Pro 2.2GHz system but was sometimes running low on memory so I upgrade to 1GB & now the swap file is seldom needed.

When a computer starts to run low on memory it starts using more & more swap file (a space set aside on your hard drive as virtual or swap memory).  This will cause a slow down in your computer.

I notice that you only have 46MB of free memory.  That may be part you're the problem.

A friend of mine had only 256MB on his Win XP system & was having all kinds of problems running programs.  Adobe Acrobat refused to run at all saying that there was insufficient system memory.  WinFax Pro was taking forever to assemble a large database to send mailings to club members.

After we added an additional 256MB to bring him up to 512MB all of those problems disappeared.  Acrobat now loads without complaint, & WinFax does the same job in 1/5th the time it used to take.

Memory is dirt cheap today & there is no reason to be running only 256KB on an XP system.

Thanks Doc, I appreciate the advice!

I'll look into some more memory.
