gcc+gcj build-times?

Wed Feb 22 13:26:00 GMT 2006

Hello all,
after some absence I tried my luck with gcj again (2006年02月18日 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.
