So, here are the results from my test. Exercise was to copy the kernel rpm from media to hd using dd.
First with CD-ROM (Toshiba FireWire DVD-ROM): Direct mount: 2327 KB/sec 6%CPU Supermount: 1321 KB/sec 9%CPU 43% performance regression Now with Lexar USB stick: Direct mount: 731 KB/sec 2%CPU Supermount: 24 KB/sec 42%CPU 97% performance regression and cpu usage jumps up by 40 percent :-( Test was done with kernel 2.4.22-23mdk-i686-up-4GB. Are there any parameters to tweak supermount? I found nothing in the ReadMe on SF.net. -- Oliver "Nobody will ever need more than 640k RAM!" -- Bill Gates, 1981 "Windows 95 needs at least 8 MB RAM." -- Bill Gates, 1996 "Nobody will ever need Windows 95." -- logical conclusion
