| |
It seems that the block device changes hit gtcd really hard:
gtcd tries to open/close /dev/cdrom several times a second, and with 2.3.45, close(fh) takes around 0.128 seconds on my Dual PII/350 with 192 MB Ram.
Actually, this means that gtcd is unusable, it causes nearly 100% cpu load on one cpu.
* open("/dev/cdrom"): identical * ioctl(CDROMREADTOCHDR): slightly slower * ioctl(CDROMREADTOCENTRY): 10* slower than 2.2.14 * close(fh): more than 100* slower than 2.2.14 * ioctl(CDROMSUBCHNL): 4* slower
I'm running gtcd version 1.0.40, as shipped with RedHat 6.1, and my CD-ROM is an IDE DVD drive.
