Hi Eric,
It is very strange indeed, but I just tested it again and I'm convinced that on my system that call can take a few seconds. I'm also pretty sure there is no concurrent access to the drive and automount is not running. I even did this on a failsafe session just to be sure, but still the same thing. I wonder there is something wrong with my kernel (2.4.18), or worse, with my computer. On the other hand, it works pretty fast on Windows.

I just realized that IOCTL_CDROM_READ_TOC is used almost everywhere in mcicda and somewhere else, but on the other hand it is as fast as a snail. A 68-track CD took 10 minutes to scan in cdplayer and if you press play, another 10 minutes will pass before it even starts playing! It appears to be a good idea to cache the TOC somewhere, but where and how?
how come you get those timings ? even if we read 10 times more the TOC as we need (so 700 times), it means the toc reading on the CD takes 600s, so basically a second for a toc reading, which could occur when the CD rom is first inserted, otherwise it's crazy questions: do you have some other apps accessing the cdrom (another playback app, automount...) ?
A+
