--- Comment #23 from Adam D. Ruppe <destructiona...@gmail.com> 2014-02-08 15:23:19 PST --- (In reply to comment #21) > Have you tried to run the D&Java benchmark attached to this Issue 9584 ? I didn't run these specifically, I just did the try/catch Jonathan wrote. Let me try them... the D one is much improved. Before: $ time ./except_d 5000 Exceptions: HI=2500 / LO=2500 real 0m0.840s After: $ time ./except_d 5000 Exceptions: HI=2500 / LO=2500 real 0m0.010s Almost 100x better in this test. This is on Linux. druntime on git already has a similar optimization for Windows, so a huge improvement should be seen there on the next dmd release too. Let's do 500,000 iterations with Java to hide the startup cost to be more fair (note my Java stuff is old, it is jdk 1.6.0): $ time java except 500000 Exceptions: HI=250000 / LO=250000 real 0m0.666s And D for 500000 runs $ time ./except_d 500000 Exceptions: HI=250000 / LO=250000 real 0m0.758s So we are a little bit slower for a large number of iterations but it is pretty close now. (BTW compiling with -O -inline etc. makes no significant difference) Certainly a lot better than before. -- Configure issuemail: https://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
