<div dir="ltr"><div>Hi Frank,<br><br></div>I tracked down the problem. The way the superbuild was calling ./configure for mesa was causing the default -O2 flags set by mesa's ./configure to get dropped, thus resulting in an unoptimized mesa build. I just merged a fix for both issues into the superbuild.<br><div class="gmail_extra"><br clear="all"><div><div data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr">----------<br>Chuck Atkins<br>Staff R&D Engineer, Scientific Computing<br>Kitware, Inc.<br><br></div></div></div></div></div></div></div>

Even better I could isolate it to the mesa build from the superbuild. Swapping out the mesa libs in the release binary on the web site, on a single 14-Core Haswell CPU I see a difference of 25MiPolys / sec with the superbuild libraries vs 118MiPolys / sec with the website binaries. That's roughly a 4.5x performance difference, i.e. not good. I don't know yet if it's a mesa problem or how we build it. I'll dig deeper and let you know.<br></div><div class="gmail_extra"><br></div><div class="gmail_extra">Thanks for the bug!<span><font color="#888888"><br><br></font></span></div><span><font color="#888888"><div class="gmail_extra">- Chuck<br></div></font></span></div>
