Hi Sascha, we are outside of my technical abilities but I tried to translate what you said and put it on the wiki. If anyone would like to expand on this please do! <a href="http://wiki.sugarlabs.org/go/Sugar_on_a_Stick/Hardware">http://wiki.sugarlabs.org/go/Sugar_on_a_Stick/Hardware</a> Thanks <div class="gmail_quote">On Tue, Jun 9, 2009 at 2:52 PM, Sascha Silbe <<a href="mailto:silbe@sugarlabs.org">silbe@sugarlabs.org</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div class="im">On Mon, Jun 08, 2009 at 08:10:36AM -0400, Caroline Meeks wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Can you give him instructions on how to gather data if he is going to be testing on school computers? </blockquote> </div> Measuring: ---------- Simple stuff (using a watch to determine time to certain events / "milestones", e.g. activities ring showing up) usually is all you want to do for more than a single or at most a few computers. With some work it should be automatable. For advanced usage I can (at least for now) only recommend to use "dstat -at --output dstat.log", always in combination with taking notes of when which events (activity started up etc.) happened (as dstat doesn't know about those and thus doesn't log them). If run in Terminal, you can use it to analyse activities. To analyse system startup you need to talk to Sebastian in order to find a way to let dstat run as early as possible. As analysing dstat output is quite some work I recommend to do this only as a second step and only for a few computers. Classification: --------------- Performance usually is dependant mostly on the following factors. Using my desktop as an example for the output of the given commands: - processor ('cat /proc/cpuinfo') - generation / connection to mainboard (Socket AM2+) - can be looked up at Wikipedia - cache size ("cache size: 512 KB") - model ("model name: AMD Athlon(tm) X2 Dual Core Processor BE-2300") - frequency ("cpu MHz: 1000.000") - on modern and mobile CPUs, the value in /proc/cpuinfo ("cpu MHz") can be the _current_ value instead of the maximum - memory size and memory bus speed ('free' for size) - "Mem: 3544060" (total, is in kB) - on-board graphics might take up some of the memory (e.g. 512MB in my case - the system has 4GB) - hard disk speed ('hdparm -T /dev/hda /dev/sda') - "Timing buffered disk reads: 226 MB in 3.01 seconds = 75.02 MB/sec" HTH.
