Use Knowledge of Your Own Threads to Extract Optimal Performance…

[Estimated Reading Time: 5 minutes] “The Delphi Geek” recently blogged about a performance bottleneck he had identified in FastMM when used with a particular conditional define. Although not directly related, his post reminded me of an experience I had many years ago, working on a highly complex multi-threaded system (long before FastMM) and the strategy we found we had to employ in order to get optimal performance from our threading code when encountering different numbers of CPU’s (these days “cores’).

Update #1 for XE2 – Get it here!

[Estimated Reading Time: 4 minutes] So I have spent about a week now with XE2 and FireMonkey and thought I would share some of the experience so far. After an initial peek and poke around, the first order of business for me was to migrate some of my existing code to the new RTL. First on the list was my own testing framework which I have been using for a few years now. Something which was on the verge of being ready to expose to the harsh light of day but which I had decided to wait until I had an XE2 (and dare I hope… a cross platform) version before releasing. So this will be the first in a number of posts dealing with specific things that I have run across. First up: Win32/Win64 cross-platform.
