#68 wontfix Performance of Java 6 is not too good yoda
Description

Java 6 still feels a quite a bit slow (in some areas). To demonstrate it, I used Jeti/2, measuring time from starting it and until GUI is up and roster and 4 MUCs (2 on local server 2 on remote) are populated.

All tests done from same client PC, only the loaded Java versions are different.

Time to start Jeti/2 until roster and 4 MUC are filled

1) 2) 3) 4)

(A lot more tests was actually done - these are the best results)

1) Java 1.41 loads in 9 secs in almost every test done.

2) Between 15-25 secs in mosts test. Not easy to see any specific

slow part.

3) Has seems to have some timing issues with sockets / DNS - hang

for a long time in same place.

4) Lots of tests were over 1 minut to load. Splash screen is

visible slowly drawn in parts. Communication with server seems to take a long time.

There seems to be room for improvement - although it may be hard to compete with our native 1.41

#69 fixed No output from java.exe -? if another Java app is already running. yoda
Description

Start any java app, and try:

Java.exe -? (no output - that is annoying)

Java.exe -version

(no output)

but

Java -fullversion

gives normal output

At least the help is needed :-)

#71 wontfix unnecessary dependence on gccxxx.dll dryeo
Description

Java includes a dependence on ftp://ftp.netlabs.org/pub/gcc/gcc4core.wpi. This can result in multiple installs of these DLLs, wasted bandwidth downloading them yet again for very little benefit. Simple solution is to set GCCOPT='-static-libgcc' This will statically link the couple of small functions that may be needed.
