DSL Ideas and Suggestions :: partimage



Are you sure dma was enabled in DSL? Is "dma" in your boot line?

Good point. Here are my bootcodes:

label Parted Magic 1.9  
 KERNEL PtMagic/bzImage
   APPEND noapic initrd=PtMagic/initrd.gz root=/dev/ram0 squashfs=/isolinux/PtMagic/pmagic init=/linuxrc ramdisk_size=100000 skip
LABEL Insert 1.3.9b
   KERNEL Insert/vmlinuz
   APPEND ramdisk_size=100000 init=/etc/init lang=en apm=power-off vga=773 initrd=Insert/miniroot.lz nomce noapic dma BOOT_IMAGE=insert
label Damn Small Linux 4.2
   KERNEL DSL/linux24
   APPEND ramdisk_size=100000 init=/etc/init lang=es apm=power-off vga=791 initrd=DSL/minirt24.gz nomce noapic qemu quiet toram BOOT_IMAGE=knoppix frugal

I will try to make dma on in DSL and come back after new trial.

Thanks for the suggestion.

I am back here!

Switched dma on in the bootcodes without improvement.

I see that Insert is using kernel 2.6.18.6 and DSL is using kernel 2.4.31

Perhaps it could influence the result?

Regards.

I don't know if he kernel version might have an effect on the throughput times for partimage, I imagine it's possible though.

I think though it's more likely to be that partimage static binary, which I guess was compiled to run on all sorts of hardware.    (Disclaimer: I'm wildly guessing here).  All optimization was probably disabled. Assuming partimage uses pthreads (I can check) that was probably disabled also.

Is your machine a dual processor machine by any chance? If so, losing threading could slow down the extension hugely, and might conceivably slow it down even if your pc is not multiprocessor.

Happy new year to WDef and all the DSL fans!

My machine is an AMD Athlon 64 3500+ at 2200 MHz with one core and one processor.

Thank you for your support. I think this issue could be useful to solve some other DSL efficiency problems, not just the Partimage case.

Regards.
