SqueakPad

Sven Schott
Just an interesting tidbit. I recently installed Squeak on my Pepper Pad 3.

 

 
It's quite nice having a touchpad with Squeak. :)

  Cool.  I played with an older one in 2004.  The result from
tinyBenchmarks was about 18,507,807 bc/s, 686,095 s/s, and it is a bit
slower than OLPC, come to think of it.  What kind of performance and
"usability" do you get?

That is cool. I didn't even know about tinyBenchmarks.

 
Pepper Pad 3 tinyBenchmarks:

 
 '28193832 bytecodes/sec; 922382 sends/sec'

 
From my MacBook Pro for comparison:

 
 '524053224 bytecodes/sec; 12262411 sends/sec'

  28 million bc/s is decent for a smaller device.  It is usually a bad
idea to draw too much from the result of micro benchmarks, but because
Squeak's VM implementation is portable across platform (and unfriendly
enough to the memory system), the result from tinyBenchmarks has been
very "proportional" to what it feels like on the platform.

  Another thing I do is something like (change the parameters as you like):

[200 timesRepeat: [Display fill: (100@100 extent: 400@400) fillColor: Color random]] timeToRun

to stress the memory band width and to see the display update
performance.
