swap file
« on: September 07, 2011, 11:25:30 AM »
Hello,
I did another installation on pentium II, 350 mhz with 256 mb
memory. i used 1 gb ssd compact flash drive connected on ide0
for my frugal installation.
I used another 1 gb ssd cf drive conncted on a usb card reader
for my swap file.
My question is about this http://forum.tinycorelinux.net/index.php/topic,1514.msg8540.html#msg8540
what would possibly happen if i continue to use compact flash drive
as a swap file. BTW, as of now i'm experiencing a slow down while
viewing you tube.

your comments and recommendations will be much appreciated

You should use a non-journalling filesystem on flash.
Swap should be on a real drive, not flash.

thanks,

for along time, i got this belief that flash disk
were faster than hard disk due to no moving
( rotating) parts.
i'll try to find my old hard drive, already misplaced.

Even if cour cf card fast, it cab be slow doue to card reader, USB connection, etc. You did not specify what is the file system type. Certain types are not optimal for such use. When it is dedicated to swap only, better to use a swap partition instead of file.

@ bmarkus
yes i agree with you. btw, i use ext4 on the said cf drive.

actually, i already made a swap partition 400mb on the
 first cfdrive where my frugal installation is. unfortunately
it is not detected. so i decided to connect another cf disk
using usb card reader.

thanks

Did you create sap using mkswap command?

Yeah, the card will die fairly fast if you use it as swap.
The only barriers that can stop you are the ones you create yourself.

ext4 is a journalling filesystem. You should use ext2 on an SD card, and mount with noatime option.

no, i created it on gparted as a swap partition because this is
how i do it on my home computer (home computer is using hard disk)
 what i do now
is reformat it to ext2 according to gerald_clark recommendation
then issue a "mkswap" in the terminal as you said.
then "swapon -a" still it's not detected but after a reboot finally it
was detected. thanks very much for your help.

Yeah, the card will die fairly fast if you use it as swap.

thanks for the reminder, i'll replace it as soon as i find my hard disk.
for now i just wanted to see TC running on pentium II. in my observation,
in you tube it's still slow and skipping frames when i check 'free'
i notice that it's not using swap that much. what could be the problem?

Flash is extremely bad software, uses cpu to no end. It's not surprising it's slow on a computer from that era.
