High system load when burning audio CDs on VIA686B
I have been having this very annoying problem of very high system load when burning audio CDs. When burning a full audio CD at 24x, I have seen the load average reach 20 -- This, on a single processor AMD Thunderbird system. top shows 90%+ system proc usage, and, although the burn works, and the CDs are playable (probably due to burn-proof), this problem still nags at me. If I drop the burn speed down to 4x, the system is usable, but, the system proc time is hovering around 50%, and, naturally, the burn is unnecessarily slow. ...I have no problems whatsoever when burning data CDs [in Linux], or when burning audio CDs with Nero in Win2k. I have run cdrecord with extra verbosity and debug flags and haven't noticed any errors, nor has there been any mention of trouble from the system logs. After googling around a bit, I found this thread: http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&oe=UTF-8&safe=off&threadm=ao9tne%2425nr%241%40FreeBSD.csie.NCTU.edu.tw&rnum=3&prev=/groups%3Fhl%3Den%26lr%3D%26ie%3DUTF-8%26oe%3DUTF-8%26safe%3Doff%26q%3Daudio%2Bsystem%2Bload%26btnG%3DGoogle%2BSearch%26meta%3Dgroup%253Dmailing.comp.cdwrite ...Which describes my problem perfectly. My system stats: AMD Thunderbird 1ghz, overclocked to 1377mhz and perfectly stable 512MB of Crucial CAS2 PC133 memory Epox 8kta3-Pro motherboard, VIA KT133A chipset with 686B IDE controller Lite-On 24x CD-RW drive Is this an issue in the kernel or cdrecord? Is it expected to be fixed soon? If not, if I put the burner on a Promise IDE controller card, would the problems subside?
