Yep, that checks out too, thanks.  For the last 6+ months, if I\'ve been up late at night, chances are that I\'ve been playing with my Zaurus.  Very addictive!

In an earlier post, you mentioned that Word started up as if it were a fastload program.  Could you give a rough estimate as to how long it takes to display the initial screen?  I\'ve tried my several times and from tap until display seems to be about 2 seconds.  Sheet is a little longer 3-4.  Unfortunately, I didn\'t time them before upgrading.  The Jeode PrimTest app does seem to start much faster.  I\'ve ignored other apps that I loaded to SD figuring that they\'d still have the load-from-SD IO lag time.

Thank you again for uploading it to the site and for the information.

Tumnus - if you\'ve still got your dev environment set up, would you be able to do us a big favour and compile a pre-emptive-patched kernel for the 5500?

Or anyone else for that matter... ;-)

Cheers,

Jeremy.

Hello, I compiled 2.4.18-rmk7-pxa3-embedix kernel for SL-5500 with preemtible and did some tests, but as you see there was no speed difference at all and with preemptible usbnet didn\'t work.

2.4.18-rmk7-pxa3-embedix

Dhrystone Benchmark, Version 2.1 (Language: C)
Register option not selected.
Microseconds for one loop:     3.7
Dhrystones per second:   267737.6
VAX MIPS rating:    152.383

2.4.18-rmk7-pxa3-embedix-premtible

Dhrystone Benchmark, Version 2.1 (Language: C)
Register option not selected.
Microseconds for one loop:     3.7
Dhrystones per second:   268817.2
VAX MIPS rating:    152.998

Which is the expected result.

I have been doing some experimenting, and it\'s not the pre-emptive patch that makes the difference on the 5600 as mickey expected  . It\'s the fact that the XScale cache errata workaround is being turned off, enabling the PXA-250 CPU in the 5600 to run at full speed. So apart from overclocking I guess there is no way of increasing the performance of the SL-5500 very much.

This wouldn\'t happen to work on openzaurus would it?   :wink:

I don\'t know about the patch, but it says that it (cpufreq which is what cpudyn uses) is compatible with the SA1110.
