SamplingProfiler run results can be saved to .spr files (Sampling Profiler Results) and later reused for comparison purposes, or for merging, one of the less obvious features of the profiler.
You can merge results by right-clicking on a results tab and selecting… “Merge results”, oddly enough. After this, the samples will be aggregated across the runs you selected, hopefully providing more statistical accuracy.
Previous host experienced downtime issues, so DelphiTools.info has been relocated on a new host. Not everything is back up in order just yet…
Update: download, screenshots & links back online, but comments seem to be lost forever…
Update 2: did some tweaking with the help of YSlow, site should be loading faster now.
Update 3: was able to access the old database, restored the lost comment.
edit: forums have since been deprecated, use StackOverflow for questions.
I’ve opened a forum for SamplingProfiler, destined for peer support and bug reports:
https://delphitools.info/forums/
I don’t have any previous experience with freeforums.org as a host, but I don’t expect the traffic to be huge, so it’ll probably be good enough.
Forums are now hosted locally.
Another channel through which you can reach me would be via posting in the CodeGear newsgroups.
One issue when trying to profile a “live” application is that you may be getting a lot of noise, resulting from a particular library or section of code being executed from multiple contexts.
You may also be after profiling only one particular case, and want some reproducibility between runs… in short: you want a finer grained control on when or for what the profiling will take place.
SamplingProfiler comes as a stand alone-application, but it’s also ready for integration in the IDE via the Tools menu. Go to the Tools menu configuration and add an entry for SamplingProfiler. Set the parameters field to $EXENAME. Voilà!
http://DelphiTools.info/ shall be the url for this page for the foreseeable future, the one you can bookmark!
When time allows, I’ll post my other Delphi-oriented tools here, hence the name of the site. For now I’ve just added a few links, I’ll be adding more and reworking the site pages as I get more familiar with WordPress.
…after having long been a ghost in the Borland attachments newsgroup, this is an attempt for a more permanent home for SamplingProfiler. Hopefully you’ll find news and download links here.
The current released version is 1.5.2 and available from Torry.ru.
A version 1.6.0 is happening, at this point it’s just a version compiled with D2009. If you are interested in testing it, leave comments here!
