Hi,<div><br></div><div>I've been porting some code from itk 3.20 to itk v4. While i can achieve numerically identical results with a little work, I'm noticing a 10-30% performance decrease overall. At this point it seems kind of generalized, i have trouble tracking it down to a specific routine or module which makes me think it may be buried in low level code.</div>
<div><br></div><div><div>It does not seem to be the GetInput issue raised earlier on the list.</div><br class="Apple-interchange-newline"></div><div>This is on Visual Studio 2005, XP, 32 bit. I do not know if it is generalized - indeed, it could easily be the case that modern C++ which compiles better on gcc and clang is confusing this old compiler.</div>
<div><br></div><div>Are there already any ITK performance benchmarks?</div><div><br></div><div>Rupert<br clear="all">--------------------------------------------------------------<br>Rupert Brooks<br><a href="mailto:rupert.brooks@gmail.com">rupert.brooks@gmail.com</a><br>
