The raw data is down below in the appendix. I'll go over the results here that I find surprising:</p> <div class="subentry"> <h3>Setter/Getters vs. Regular Instance Functions</h3> <pre> // Setter/Getter p.XVal = 23.4; // 25 msec / 1000 x = p.XVal; // 12 msec / 1000 </pre> <p align="center">vs.</p></pre></div> Performance ActionScript Fri, 11 Apr 2008 18:48:43 -0700 http://www.connectedpixel.com/blog/performance/impact/oo <p>While writing that animated sine-wave thingy at the top of my web site, I ran into a problem -- my frame rate was terrible. I was getting maybe 3 or 4 frames a second. My browser was bogging down, my computer was bogging down. I had to either speed it up, or I had to dump it.</p> <p>As it has many trig calculations in each frame, I thought that Math.sin() was to blame. I was getting ready to write a table-lookup algorithm to replace Math.sin, when the little angel on my shoulder told me to quit guessing and be more scientific about it. So I wrote a test program instead. I found that Math.sin was extremely fast and certainly not the cause of my problem.</p> Performance ActionScript Fri, 11 Apr 2008 18:49:06 -0700
