Trying to burn/Copy CDs on -the-fly -Suse 9.2 ,What CPU/hardware needed???
 

:confused:

Hello Linux Heads ,trying to figure out WHAt requirements do Ineed to burn CDs on the fly with Suse (8.2 up to 9.2 and (10.0-open suse) .

My present hardware is Intelceleron 700 <o,clocked to 800>. 384 mb PC 100 sdram , Matrox 2164w Vidcard , EPOX MObo (via 694 chipset). 420 Watt generic Supply., My dvd drive is a Hitachi GH series ,,CD-r is a Iomega 4x8x32 ,to my best memory . The CDdrives are on the Second IDE channel . Hard drive on Primary ide.



In the Recent past (since 2005 when I built this box ,I used K3b to copy cds . However ,Ihad a strange setup where as the Primary ide channel First had a dvdrom as boot device,then Hard drive (with Suse -<slave>. and second ide had Cd-rdrive and second hd<unused . as Slave

My way of copying CDs was using a swap file in the assigned Tmp directory as K3b likes to do so.

It worked fine for years ,but was SLOW (had a Celeron 400 in it!!). Took 45 minutes to do a CD ,but sounded flawless?!!

But in the past few months ,it started screwing up ,taking Forever to copy a disk , I figured it was Copy-protected CDs ,but with a Software tool called Partition Commander, found out part of the Hdrve is damaged ,probably swap file for k3b??!!!


So thats my story


Is this TOO slow+sloggy to do on -the fly cd or even vob transfer


Adios ,chili

Well yeah - for on-the-fly you need lots of RAM mostly, and a fast bus.
Your celeron 700 is very old now, you really just want any modern computer.

Note REDHAT 6.1 is also very old, there has been no redhat linux distro in a long long time - what about RHEL 5.5 instead (RHEL 6 is still in beta, if you are game).

On -the fly -redux!!!!!!!!!!!!!!!
 

MY total story of this setup..

If I am not providing useful information, please rephrase your question to target the info you want. Reproducing the original post will not change the answer. However, I'll take a stab at guessing what you are after...

To recover your old performance on that machine, you'd start by repairing the damaged fs. fsck is your friend here - If, as you suspect, you have a corrupted swap file... just make a new one and see what happens. However, this sort of thing is a sign of progressing drive failure - it will only get worse - backup now and replace the disk. But you did not explicitly ask about any of this.

The question you asked was about what HW you'd need to do "on the fly" audio and video processing. (Specifically burning CDs but you also mentioned VOB files.) You were interested in performance but you were not specific about the exact processing you wanted to do.

I stand by my reply: your HW is getting too old. You need a modern computer.

If you put the swap file in RAM instead of on the HDD, the process would be faster. Thus the comment about RAM being important. Overclocking experiments also show that the major limiting factor in modern computer speed is not the CPU but the bus speeds.

I don't ever burn CDs or DVDs on the fly, the reason being that if at the time something is using your HDD intensively, the burn may fail. With CDs this will NOT happen if you have burnfree enabled (so check if your drive has this). With DVDs a large buffer will help prevent this. However, I still don't do it, because I've had burns fail due to buffer underrun (at least for DVDs).

I also think that you HDD is too old and probably failing, like stated above.

Dude ^everyone^ is right...your HW is way outta date. You need CPU powwa + fast bus/disk I/O.

Can't remember last time I 'copied' a CD. I do use abcde cmdline to rip audio cd's to mp3. I use k9copy to rip DVDs. All this on a MD RAID0 stripe across 2 1TB SATAII drives mounted w/XFS using -noatime switch, dual proc 2.5Ghz, x64 Ubuntu. I'm gettin around 100MB/sec disk write speed even after tweaking w/hdparm/sdparm trix (turning off read-lookahead, read-cache, etc). My bottleneck now is three-fold...1. the old CD/DVDrom drive and the HD spindle speed (7200RPM) and the cheez onboard SATA controller (read fake raid).

To address my disk I/O bottleneck, I'm seriously considering pickin up:
- SDD HD
- SATAII PCIe controller for the SDD HD
- updated DVDrom drive

HEY FuuBAR 2003
 

:twocents: Hello there Fuubar ,whoever you are ??

You seem like the real Heavy Linux Junkie type w/that exotic hardware.

Out of Curiosity ,what Brand/model MOBo(motherboard) are you using??

Dual processors for this????? I surmise you are using a Server MOBO.

This is a system that sounds like bigBucks , but is neccesary for the Dvd applications.

adios ,chilibowl

nah, not exotic and not srvr hardware.

Filesvr: Intel Desktop DG45FC mobo (microATX) w/Intel DUAL CORE E5200 2.5 GHz, w/4GB DDR2 667 RAM
- 2 Samsung HD103SJ 1TB 7200 RPM 32MB Cache SATA harddrives with md software raid 0 stripe, xfs filesystem
- the dvd burner is an older Sony 24x
- Ubuntu
- Antec microATX cube case

VMware svr: M2N78-LA microATX mobo w/AMD Phenom II Quad core w/16GB RAM, 1TB 7200 RPM Western Digital SATA harddrive
- SLES11

The fileserver HW is a bit older. It stores dvd's in iso format and mp4. Using apache I srv a web page with links to the MP4 movies to srv to my ipod itouch via wireless. The iso's can be mounted/played on my laptop which can connect to the TV...but that has to go over the LAN as my wireless base station is way old and cannot handle the traffic. To rip dvd's any faster, I'll need a better harddisk controller and faster harddisks. Like I said b4, I'd like to get some SSD drives and a SATAII controller. Would definitely shift my bottleneck around.

The VMware svr could rip movies too, I should probably put any newer HW on it since it is a lot newer than the filesvr HW.

Thanks for correcting ME!!
 

Hardware?!!
 

:study: Hello FUUBAR again , I myself was considering using SErver Hardware ,only to find out/study that the IDE Channels in many older server MOBO,s have a bottleneck in the ATA100 or ata 66 choices ,since most IDE cd/dvd roms/ burners have at least ata 100/133 compatibility. If I hooked them up to a MOBO w/ ata66 I figure CD/dvd reading /burning would suffer.


I often wondered if the transferral from SCSI -hDdrves to CD-rs /dvd-rs would even work in burning /copying processes.

Thanks for your reply ,FUUBAR

adios ,chilibowl

No currently available CD-/DVD-burner or -reader is able to receive/deliver data at a rate that would outperform even ATA/66, so this should not be a bottleneck. And of course, it is no problem to burn data on a CD/DVD that is delivered from a SCSI- or SATA-harddisk.

Have you checked if DMA is enabled? If it isn't, enable it and see if things improve.

To see if it is on:

To turn DMA on:

Bottleneck??!!
 

Really ,than why do they put ina IDe ata/ 100 chip 0r spec???

SATA is the fastest way ,right???? ide is becoming oLD!!???

Iam used to ide.not sata.


My good ole windows xp box believe it or not has a Pentium 3 1.26 g w/768 mb yte ram and ide for the channels ,very few problems with Nero burning or IMG burn. However its no state of the art Hot Rod, but did the trick.

Ithink it worked under Suse9.2 w/k3b a few tymes. :study::hattip:


But I would rather save it for windows.

Time to move on ,,,,


adios ,chilibowl

For marketing issues. A burner with SATA- or ATA100-interface will not be faster as a burner with ATA-66 interface. Think a minute: If you burn a cd with 52x-speed, or a DVD with 16x, how could it be faster on the newer interface?

I think the HDD and filesystem matter a whole lot more than the DVD drive and interface. You have to get that data from the disk, and if the disk is doing something else or is very busy, you will burn a coaster, without burnfree of course.
