<div dir="ltr"><div>Hi, </div><div><br></div><div>I compared compilation time with clang version 3.5 that ships with latest ubuntu and the one I built (with --enable-optimized --enable-shared). The results are:<br><br>3.5 from ubuntu: 2,60s user 0,14s system 99% cpu <b>2,766</b> total</div><div>3.6 (a33591f612fa56e7c83fe348e7ca6c32778aacb0): 3,92s user 0,14s system 99% cpu <b>4,078</b> total</div><div><br></div><div>Did run the same compilation few times with the same compiler to avoid some cold caches.</div><div><br></div><div>This means almost 50%. Any reason for this? Any other build hints for more aggressive optimizations?</div><br><div class="gmail_signature">rgrds,<br>mobi phil<br><br><br><br></div>
