Ultralite & sloooow PalmOS Emulator
Greetings We are developing an application for palm with Ultralite support (sybase). There is one big problem. Synchronizing with emulator takes more then 1 hour. I would believe that it takes so much with real palm connected by serial cable (not tested), but why is the emulator so slow? Saved PDB after synchronization is about 1.2 MB long. Does anyone know how to make emulator faster? btw, we have much more problem with ultralite (sometimes Open crash, or Dr.Watson kills emulator while trying to Close() some table and much more...) Can anyone sugest some workaround to make it run better? (or any conditions we have to fulfill...) thnx for help, bye -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/

Solutions to your stated question (easiest to most difficult): 1. Use a release ROM instead of a debug ROM. The debug ROMs contain error-checking code that slows down many system functions. This is usually what you want when writing code, but you can use a release ROM if you just want more speed (you won't get the added checking). 2. Get a faster computer. 3. Optimize the POSE source code. I suspect your effort/return ratio will be pretty high with this approach. I would perform the sync with a real device - you might find that the problem has nothing to do with POSE at all. The bottleneck might be in Ultralite or the HotSync process. The comments of others here will be a poor substitute for your own empirical data. JB -- JB Parrett [EMAIL PROTECTED] Palm, Inc. We grow a lot faster than trees, so we miss a lot of stuff. - B.

I'm going to take a guess here that the database you are syncing contains many records. Each record cotains overhead, and requires a separate write when syncing. If you were able to pack many smaller records into larger ones, the speed of the sync would increase dramatically. -- Brian Mathis Direct Edge http://www.directedge.com -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/

> but why is the emulator so slow? What makes you think it's slow? It's doing a lot of stuff! What makes you think it should be any faster than it is? Once you do your comparisons, I'd be interested in seeing how long it takes to: * HotSync with Poser using Network HotSync * HotSync with Poser using a serial loopback cable * HotSync with an actual device using NetWork HotSync * HotSync with an actual device over a serial cable In the first two cases, it would also be interesting to know what kind of host computer you're using. -- Keith Rollin -- Palm OS Emulator engineer "Michal Seliga" <[EMAIL PROTECTED]> on 09/12/2000 03:56:48 AM Please respond to "Palm Developer Forum" <[EMAIL PROTECTED]> Sent by: "Michal Seliga" <[EMAIL PROTECTED]> To: "Palm Developer Forum" <[EMAIL PROTECTED]> cc:(Keith Rollin/US/PALM) Subject: Ultralite & slw PalmOS Emulator Greetings We are developing an application for palm with Ultralite support (sybase).
