PROFILING WITH DBUG
.R
.P
With
.I dbug
one can do profiling in a machine independent fashion,
without a need for profiled version of system libraries.
For this,
.I dbug
can write out a file
called
.B dbugmon.out
(by default). This is an ascii file containing lines of the form:
.DS CB N
\fC<function-name> E <time-entered>
<function-name> X <time-exited>
.DE
.P
A second program (\fBanalyze\fR) reads this file, and produces a report on
standard output.
.P
Profiling is enabled through the
.B g
flag. It can take a list of
function names for which profiling is enabled. By default, it
profiles all functions.
.P
The profile file is opened for appending. This
is in order that one can run a program several times, and get the
sum total of all the times, etc.
.P
An example of the report generated follows:
.DS CB N
\fC
Profile of Execution
Execution times are in milliseconds
Calls Time

Times Percentage Time Spent Percentage
Function Called of total in Function of total Importance
======== ====== ========== =========== ========== ==========

main 1 16.67 0 0.00 0
======== ====== ========== =========== ==========
Totals 6 100.00 30 100.00
.DE
.P
As you can see, it's quite self-evident. The
.B Importance
column is a
metric obtained by multiplying the percentage of the calls and the percentage
of the time. Functions with higher 'importance' benefit the most from
being sped up.
.P
As a limitation - setjmp/longjmp, or child processes, are ignored
for the time being. Also, profiling does not work
in a multi-threaded environment.
.P
Profiling code is (c) Binayak Banerjee.
