Knoppix Performance on USB with ReiserFS
Hi people, this is my first post of this forum; i have experimented a knoppix configuration in a ReiserFS formatted USB Stick, where the performance and boot.
I Have not used the "flash-knoppix" script, because it only creates FAT32/vfat filesystem. So i firstly did a mkfs.reiserfs on there, then manually copied Knoppix files. After that i copied the grub directory from a knoppix environment (/boot/grub) and ran the grub shell to install manually on the MBR of that USB Stick. Then i edited the grub file manually with my desired options for boot.
The result is that the knoppix boot only took nearly 15 seconds, and the knoppix persistent image only 3 seconds :cool: (Note that my laptop is a dell inspiron 1525 with 2GB RAM and 2.1 GHz dual core CPU, also without a hard disk connected)
These steps are very useful.
Here's how I go about estimating 'time-to-online'
.
Estimating time to on-line with wifi:
I use ntpdate, and have /var/log/syslog re-activated.
You can use Synaptic to add ntpdate.
If you need to re-activate syslog, see my 'Tweak #3' at:
http://www.knoppix.net/forum/threads...ghlight=syslog
I have added a hidden file '~/.bashrc, (in /home/knoppix) which contains:
alias sl='less /var/log/syslog'
alias timeto='sl|grep -m 1 ntpdate; sl|grep restart'
Open up a terminal to 80 columns, enter 'timeto' and look at the first 15 characters
in each of the two lines. If you subtract the minutes and seconds,
and disregard the (your.hrs) hours difference between (your.st)ST and GST,
then that is my estimate of the time it takes to get on-line with wifi.
Using 'Class 2' SanDisk SD Cards, I get about 43 seconds.
Class 2 means 2 Mb/sec minimum, but nominal r/w speed for these inexpensive cards
are not specified, nor guaranteed by SanDisk.
