gcc+gcj build-times?

[Norman Hendrich <hendrich at informatik dot uni-hamburg dot de>]

Hello all,

after some absence I tried my luck with gcj again (2006.02.18 snapshot).
However, it seems that I did something wrong:

1) building gcc 4.2.0 20060218 (C,C++,Java) took over _three hours/
   on my Athlon 2600+ machine. For comparison, I last built gcc/gcj
   before the classpath merge, which completed in about 35 minutes (iirc) 
   on the same machine. This is on gnu-linux-x86 with gcc-4.0.0 as my 
   system compiler.
   
   Is this normal?   
   
   
2) I "only" have 512 MBytes RAM on this machine. Building gcj (both
   "make" and crazily also "make install") required a smidgen more than 
   512 megs with corresponding swapping and an unusable machine during
   several minutes.
   
   Is this intentional?  Do you get provision from DRAM vendors? :-)

   
3) The resulting compiler seems to work, but AWT/Swing performance is
   not what I expected. Actually, jamvm+classpath runs some of my test
   apps faster than gcj -O3 ...  see next post for an example.


Any insights as how to speed up build-times or why AWT/Swing might 
end up crawling under gcj are really appreciated.
