…is as important as knowing how to optimize.
In this thread on the Delphi forums Ante Bonic brought back to intention this excellent Delphi Optimization Guide in Delphi article by Robert Lee. The article has aged a bit, but many tips remain true with the Delphi 2009 compiler (sadly so).
SamplingProfiler v1.7.1 is now available, it fixes the crash in the paths dialog reported by Kazan in the forums.
Incidentally this was due to a very old Delphi 5 bit of code that somehow survived Delphi 2009 at the compilation level, but bombed at runtime… I dropped the code and made use of the already existing D2009 version, hence the smaller executable.
For further details on this version, see the v1.7.0 post.
SamplingProfiler v1.7.0 is now available, you can get the zip and release details from its changelog page.
As announced last week, the changes are a fix for a bug that could drastically affect the execution speed of the profiled application when relying on MAP files for debug information, if you were hit by this bug, things should be like night and day with this version (and hopefully I didn’t break anything else in the process…).
MapFileStats v1.2 is now available for download, it fixes reported issues and introduces a few minor improvements, such as using the ability to abort search paths scans and remembering MAP File and Search Paths options between executions. You can find the complete list in the changelog.
This morning while debugging a statistical ichthyo-parser I stumbled upon what looked like a Delphi 2009 compiler bug: the compiler was outputting gibberish ASM opcodes… But after further investigations, it appeared this wasn’t completely gibberish, but that it was (somewhat) correct MSIL bytecode!
