Some more information about my slow compiler: I'm running on a dual-core HP workstation with 4GB of RAM. I try to limit what else I'm running (usually just Excel and Firefox) and I've been watching Task Manager without noticing anything remarkable.
More recently I've been forced to work offsite on a laptop (dual-core 1GB) and the performance is a little slower. The desktop and laptop were setup completely differently with different versions of Windows. However, I was too lazy to reinstall Eclipse so I just copied over C:\eclipse (including the workspace) from my desktop to my laptop. Clue #1 - it's probably more to do with my Eclipse than my computer. Small applications compile quickly. The problem grew slowly worse over time - after a month I was forced to abandon the "Build Automatically" option. I haven't integrated my application, so right now it is a series of individual MXML files running by themselves in the browser (all within the same Project). Most files "import" other classes, and a couple "include" other files in a pretty ugly way. But I would have thought keeping them separate like this would reduce the compilation time. I'm not including any graphics in my application yet. But I do Embed a couple of XML files at compile-time. One of them is reasonably large (8,000 lines) and I dread changing it because the application will only see it after a full recompile. Next to those individual MXML files, the only thing that has consistently been growing is this Embedded XML file. Clue #2 - maybe the compiler doesn't like Embedding files? I'll work on doing that other stuff you recommended - compiling with ANT/MXMLC, and generating the line count. I might also try upgrading Flex Builder. If none of that works, I'll take you up on your offer (Matt) and send you the source code. All the best, Ted. --- In flexcoders@yahoogroups.com, Tim Rowe <tim.r...@...> wrote: > > With over 2,000 source and resource files in our application (just the > client-side is 1k as, 500 mxml, there's another 8k8 .java on the server > side), our compile time is under 30 seconds (on a C2D 2.33 w/4GB), so I would > hazard a guess something's wrong. > > A few things to check/do: > 0.
