Hello,
I have a performance problem writing audio discs at 16x in Linux. Cdrecord 1.11a17 can just barely keep its fifo filled during the burn, mostly. Data burns are not a problem, 12x audio burns are also not a problem, or it seems I have barely enough horsepower to manage that, but burning from mp3s with on the fly decoding again has performance problems. Same problem happens when burning video-CDs with cdrdao 1.1.5, 12x fine, 16x problems. Top doesn't show any application taking very much CPU. Burning in Windows 98SE with cdrecord 1.11a12 and Nero 5.5 is ok, even decoding mp3 on the fly and burning at 16x. System is Duron 800, MSI K7T Turbo-R motherboard (VIA KT133A), writer is LG GCE-8160B, Linux is Debian Testing, kernel 2.4.19-pre2-ac2 at the moment, I've tried 2.4.16 and 2.4.17 as well, with and without preemptive and ide-patches, doesn't matter. Two HD's, one on primary master, the other on the on board Promise 20265 "raid". Doesn't matter which HD I burn from, chipset support is on for both controllers in kernel. Writer is secondary master with a Toshiba CDROM as slave, but I dont't burn from that. DMA is on for all drives. Turning it off causes further slowdown. I've heard from someone else with the same writer with the same problem, although he says he can't burn audio faster than 4x without problems. Output from a burn follows (cdrecord dev=0,0,0 speed=16 -dummy -v 01*wav). Any ideas? scsidev: '0,0,0' scsibus: 0 target: 0 lun: 0 Linux sg driver version: 3.1.22 Cdrecord 1.11a17 (i686-pc-linux-gnu) Copyright (C) 1995-2002 J�rg Schilling TOC Type: 0 = CD-DA Using libscg version 'schily-0.6' atapi: 1 Device type : Removable CD-ROM Version : 0 Response Format: 2 Capabilities : Vendor_info : 'HL-DT-ST' Identifikation : 'CD-RW GCE-8160B ' Revision : '2.01' Device seems to be: Generic mmc CD-RW.
