Hi Volker,
The problem is the following: When creating a file we have to prove that the file does not exist in a different upper/lower case combination. Under Unix, the only way to prove this is to list the whole directory and do a case insensitive comparison on each existing file.
Thank you SO much. Your suggestion totally solved the problem. It makes sense when you think about it.
Results: When capturing standard definition DPX files, CPU utilization is now down at 7 percent (out of 400 percent) and holds steady forever basically. I was able to capture 150,000 frames (83 minutes) before I got bored and stopped my test. In addition, I'm now capturing HD-444 DPX files which run at about 260 MB/sec and that's doing fine as well -- running at 37 percent total CPU (out of 400 percent).
