Performance Drops With Batch Processing

I'm trying to batch thousands of files and it is becoming an increasingly difficult task. I'm loading about 100 files into the batch processing window and running a Favorite with just 2 fairly simple tasks (Noise/Hiss reduction, Speech Volume leveler, Save to Mono Mp3) and it is taking 4-6 hours to finish each batch of about 100 files. Files are typically 8-12 minutes of stereo CD quality audio.  If I run those tasks on one of the files individually it takes about 20 seconds for the effects to be applied, and another 20-30 seconds to save. When I try to run those as a batch on the files the computer slows down to a crawl. Audition will slowly tick upwards in memory usage, processor usage stays below 5%, and the computer grinds to a complete halt and becomes unusable.

The only way that I'm able to make any progress is by loading 5 or 6 files in the batch process, which finishes in just a few minutes.

I noticed that Audition is trying to apply the effects on about 6 of the files all at the same time, is there a way to stop that? Seems like the problem starts when audition tries to add the hiss reduction effect on 3 or more files at the same time.

Most of my processing has been over a network (files pulled from one computer, rendered to a NAS), I tried to doing everything locally and had no change in performance.

Computer specs:

i7 3770 3.4 Ghz

8 GB Ram

Win7 64 bit

Any suggestions are welcome.

    Edit>Preferences>Data and set the maximum number of concurrent file processes to 1 instead of the default 3 is the only thing that I'm aware of that you can alter in this regard. I've no personal experience of what this will do to batch processing, and if it makes a difference at all, we'd be delighted to hear back...

    Can you share your batch processing settings (input file types, output file types) and effects being added?

    I'm currently looking at that area in response to a different bug report. So this would be very timely.

    WAV -Stereo - 44.1khz - 16 Bit

    Effects added:

    Channel Mixer (mix down L/R Stereo to mono)

    Let me know if you need any more info. I still have thousands of files to batch so if you need someone to beta test for ya

    Thanks for sharing that. However, I wasn't very clear in my request. Sorry about that.

    Would you be able to send us your preferences folder (which would have the last-used batch settings) and a selection of files (a dozen or so should be fine).  If you're up to that, please send to audbugs @adobe.com and reference this thread.

    Wow, I'm embarrassed. Exactly what I was looking for, fixed the problem. Each file is taking about 25 seconds now.

    Thanks Steve
