java 5 slower?

Classic Servoy
1

I installed java 5 on one of my computer s(just client testing!)
Did anyone experience that a client with java 5 is slower than the same client with java 1.4.2??

The screens are build much slower the first time! After the screen is build the speed good, but every screen is slower!

I thought Java 5 would be faster!

Sorry - this is not really an answer but more some related questions.

I have a win 2k server running Servoy 2.2 and MS SQL Server 2000 with Java 1.4.2

All PC clients are running Win XP SP2 and Java 1.4.2. Some of the PCs are slow, but they are only 500Mhz P3’s with 256Mb RAM. The faster PCs are fine.

All Mac clients are running Panther (OS 10.3). The Macs are all slow, but then they are all G4s with 512Mb RAM and mostly c 500Mhz processors.

2 questions…

  1. Does anyone know if I’m likely to have problems if I upgrade the server and all PCs to Java 1.5 and leave the Mac clients on Panther/1.4.2?

  2. Eventually I am planning to upgrade the Macs to Tiger and Java 1.5 - is this likley to speed up Servoy on the slower Macs?

Not sure if Java 1.5 under Tiger is faster than 1.4.
Anyway, java under Tiger seems to be much responsive than under Panther, so your mac clients should benefit of the upgrade.
Moreover, under Tiger you can easillyy switch from 1.4 to 1.5.

As a follow up to this discussion, I have a couple of questions which I mistakenly posted under SQL databases before.

  1. How does one actually install or set java and/or Servoy so that it runs Java 1.5 when running Servoy developer from terminal under Mac OS X.4? Setting it up so that it runs when double-clicking the Servoy application is simple (through the java preferences.app that comes with 1.5). But when you run Servoy from the command line in terminal (‘java -DSTACKTRACE=true -jar servoy_developer.jar’) that doesn’t do it. Servoy in that case is using 1.4.2. Any thoughts?

  2. I almost always use the command line to start up Servoy Developer because a) that way I can see what’s going on without having to go to the log and b) startup is MUCH faster - 30 secs vs 150 secs. And that relative percentage is true on my g5, my g4 and my powerbook g4. Can someone tell me why that is? Is there any downside to starting up using the command line? The behaviour seems identical to me other than it is so much faster using the command line and one can see what is going on.

Any help would be greatly appreciated.

For anyone interested I have a workaround for launching Servoy developer from the command line using Java 1.5 with Tiger. From your Servoy directory:```
/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/home/bin/java -DSTACKTRACE=true -jar servoy_developer.jar
