I've found that using CFX_OpenImage rescales images about 75-90% faster and creates images that are about 64-72% smaller than CFImage. Simply getting the image dimensions is about 96% faster. http://www.kolumbus.fi/~kr0626/cfx_openimage/ (NOTE: Only available for Win32) Two years later and nothing has really changed even with CF9.

If you want to add tests that target CF8 behavior please do! Regressions from CF8 to CF9 are really bad, and should be tested too. @Brandon

If a variable already exists and you reassign with a chain it creates structs for the entire chain. Your personal style shouldn't mean anything to what the language supports. You may not like it, but I know lots of developers that depend on that behavior in CF, and if CF9.0.2 broke it that'd be really bad. Railo doesn't currently implement this behavior, but there's no performance hit with creating missing struct keys instead of throwing exceptions. All that said, I've refactored the tests to test that behavior separately. This testsuite is about exposing language regressions or glaring holes in support, like Railo not supporting the dollar sign in function metadata names or Adobe evaluating expressions in the wrong order. I'm very open to splitting tests apart to smaller ones based around runtime support. You'll notice there's already a special test for function collisions in Railo vs Adobe CF. Please do submit more tests too! @Mark
