This is what I did: #cd mauve #mono ../ikvm/bin/ikvmc.exe -out:mauve.exe -main:gnu.testlet.SimpleTestHarness `find | grep -v altered | grep .*class$` -reference:../ikvm/bin/classpath.dll #cp ../ikvm/bin/*.dll . #time echo gnu.testlet.java.lang.Character.unicode | mono mauve.exe -debug Reading unicode database... done Benchmark : load:2151ms tests:328ms 0 of 3578944 tests failed real 0m2.979s user 0m0.030s sys 0m0.050s On Windows I got: C:\mauve>echo gnu.testlet.java.lang.Character.unicode| mono mauve.exe -debug Reading unicode database... done Benchmark : load:1763ms tests:731ms 0 of 3578944 tests failed C:\mauve>echo gnu.testlet.java.lang.Character.unicode| mauve.exe -debug Reading unicode database... done Benchmark : load:180ms tests:170ms 0 of 3578944 tests failed C:\mauve>echo gnu.testlet.java.lang.Character.unicode| ikvm gnu.testlet.SimpleTestHarness -debug Reading unicode database... done Benchmark : load:180ms tests:170ms 0 of 3578944 tests failed So for the run time it doesn't make any difference if it is precompiled or not, total time is a bit longer though (about 1.5 second versus 1.0 seconds). Note also that IKVM running on the Microsoft framework is faster than Hotspot (but overall elapsed time for Hotspot is less, about 0.7 seconds): C:\mauve>echo gnu.testlet.java.lang.Character.unicode| \j2re1.4.1\bin\java gnu.testlet.SimpleTestHarness -debug Reading unicode database... done Benchmark : load:220ms tests:250ms 0 of 3578944 tests failed All tests are on a 1.7 GHz Pentium M, the Linux test was running in a VMWare session. > The other thing to try would be using Mono's --aot option > to pre-JIT (as it were) the generated exe and dlls. I couldn't get that to work. Regards, Jeroen _______________________________________________ Classpath mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/classpath
