SamplingProfiler was initially released in the Delphi ASM newsgroup, and I’m curious about the audience of this website, so I’ve setup a small poll.
How familiar are you with code profiling and/or Delphi code optimization? Can you tell apart instrumenting and sampling profilers merely by their respective heisenbugs, or is that profiler business sounding like a TV series from the last century?
Still hot out of the D2009 linker is v1.6.1 of SamplingProfiler.
This is essentially a bugfix release which should solve the Win2k compatibility issue.
There will come a time when SamplingProfiler may report you that begin or end are your bottlenecks. This may sound a little surprising, but it’s actually quite a common occurrence, and something that instrumenting profilers are not going to point out, so it might be worth a little explanation.
Version 1.6.0 of the Delphi sampling profiler is now available from its downloads page!
The main addition is the ability to have sampling conditioned by CPU usage, ie. only gather profiling information when the CPU usage is high, either for the system or the process.
This was added with three goals in mind:
I’ve reorganized the site a bit since the relocation, tweaked WordPress behind the scenes, added OpenID support for comments and hopefully sorted out the over-aggressive spam filter.
The support forums are no longer available now also hosted here, no OpenID support for them just yet, but I’ll enable it as soon as it’s out of beta. For bug reports and features/suggestions, the forums are the place to post (easier to track things).
There will likely be a new SamplingProfiler release in the next days, which will add support for CPU-usage-based sampling, ie. profiling only takes place when the CPU usage goes above above a treshold (either at the system or the process level).
