Before going through the hassle of rebuilding/re-installing to try your experiment, I thought I'd look at the code. Jeez. No wonder. In 1.0.7, System.arraycopy() was a native method, defined in libraries/clib/native/System.c, which used the platform's memmov/memcpy functions. Now it's a Java implementation. Certainly easier to maintain that way, but it's unsurprising if it's more than 5 times slower. _______________________________________________ kaffe mailing list [EMAIL PROTECTED] http://kaffe.org/cgi-bin/mailman/listinfo/kaffe
