Update of this page: February/28/2000
Compiler versions:
ProDelphi supports Delphi 2/3/4/5.
Conditional compilation:
Fully supported. Compiler symbols and
switches are read from the compilers option file (DOF).
Coverage profiling:
A browser can display all methods which
were not called. (For a line-by-line coverage tool have a look at my link
page).
Customer suggestions:
Many customer suggestions have been implemented
in ProDelphi in the last versions.
Documentation:
ProDelphi comes with a real User Guide
(and not with slim online help).
Exclusion of parts of
the program from measurement:
Units or Include files:
Granularity:
ProDelphi measure in CPU-cycles. The
smallest measurable unit is 1 CPU-cycle. This means that on a Pentium
with 500 MHz the smallest measurable duration is 0.002 µs
Handling of idle times:
Idletimes produced by some Windows-API
calls are not measured, also idletimes of some Delphi calls. See list of
handled functions in the manual.
History function:
ProDelphi comes with a built-in history
function. The viewer shows by a colored grid, which functions got faster
and which got slower since the last storing of results into a history file.
By a mouse click on a result line of the viewers grid, the excact time
is displayed for the selected procedure.
Industrial approvement:
ProDelphi was used to optimize the SIEMENS
- SCADA-system VICOS P500 for the projects Metro Guang Zhou, Shen
Zhen and Sixth Railways in China.
Integration into the Delphi
tools menu:
If ProDelphi is installed with the setup
program, it is automatically integrated into the Delphi tools menu.
Local Procedures:
Fully supported.
Measuring programs with
threads:
Supported, but with less accuracy.
Measuring runtimes in
DLL's:
Fully supported
Measurement accuracy:
ProDelphi measures very accurately. The
measurement overhead is automatically removed from the measured times.
A sophisticated algorithym calculates the runtime used for measurement
at initialization time.
Measurement results:
The measured durations are displayed either
in CPU-Cycles or in a variable time format. Following time formats are
automatically selected:
Object orientation:
Specially supported by the feature of
adding the runtimes of all methods with the same name (if the used object
is the same).
Example: A method 'LoadFromDisk' calls
the method 'LoadFromDisk' of the inherited class. In this case the runtimes
of both classes will be added.
Online operating the measurement:
Measurement can be switched on and off
at the programs runtime, also results can be stored online. This speeds
up the opimization process.
Operating systems:
ProDelphi is compatible to Windows 95/98
and Windows NT.
Optimization option:
The optimization of the Delphi compiler
is automatically deactivated if the user forgets this. This guaranties
high measurement accuracy.
Professional version:
ProDelphi is available as a Freeware
or a Professional version.
Profiler type:
ProDelphi is a source instrumenting profiler.
Source instrumenting has the big advantage, that at the best position possible
a time stamp can be taken: At the start and the end of the procedure body.
No profiler internal code outside the procedure is called before taking
the time stamp. No profiler code has possibly to be copied into processor
cache before taking the time stamp (which destroys the accuracy). The normal
instruction flow (nearly identical as without profiling) is kept. This
is one of the reasons for ProDelphi's outstanding accuaracy.
Sampling profilers: with a low sampling rate small procedures can not be measured, with a high sampling rate the profiled program has to be interrupted very often, what means, that the runtime behaviour of the tested program is changed very much.
Programming-API:
Measurement can be switched on and off
at runtime. Intermediate results can be stored on disk.
Security:
ProDelphi inserts statements into the
source files. If this process has a bug or in case of power failure, the
sources might be destroyed. It is strongly recommended to save all source
code files before profiling (e.g. by WinZip).
Setup:
ProDelphi is delivered with a easy to
use setup program. It copies all files into the appropriate directories,
integrates ProDelphi into the Delphi tools menu and creates an entry in
the Windows list of programs (Start menu / Programs).
Switching on and off of
measurement:
Simply done by deleting a compiler symbol
and recompilation. At runtime this is also possible by the online operation
window. Also intermediate measurement results can be stored at runtime
(see also Programming-API).
Upgrading:
If you decide to use ProDelphi, you can
download any upgrade or bug fix from my homepage. If you need ProDelphi
for a larger project and 30 measured procedures are not enough for you,
you can order the professional version via ShareIt registration service.
If you do so, you can also download new versions from my homepage for free.
These will automatically run as professional version. (Buy one -
get many).
Viewing of measurement
results:
Results can be either displayed in CPU-cycles
or in a variable time format. On a pentium with 500 MHz the smallest time
unit is 0.002µs.
ProDelphi has THREE possibilities of viewing
the measured runtimes:
Y2K compliance:
ProDelphi is fully Year 2000 compliant
