.TH PROF 1.SH NAMEprof, wm/prof \- profiling limbo programs.SH SYNOPSIS.B prof[.B -bflnve] [.BI -m " modname"] ... [.BI -s " rate"] [.BI "cmd arg ..."].PP.B wm/prof[.B -e] [.BI -m " modname"] ... [.BI -s " rate"] [.BI "cmd arg ..."].SH DESCRIPTION.I Profis a simple profiling tool which calculates the percentage of time spent on a particular line of limbo source or spent in a particular limbo function. It can determine where a module or set of modules is spending its time. The source inquestion should be compiled with the .B -gflag so that the relevant symbol table files exist..PPThe tk version of the profiler.I wm/profshows this information in a text widget and colours the lines of source accordingto the amount of time spent on each line. The darker the colour, the longerspent..PPThe.B -boption starts profiling..PPThe.B -foption shows the function profile..PPThe.B -loption shows the line profile. If neither this option nor the.B -foption are given, .B -lis assumed..PPThe.B -noption lists the name of the file along with the line number..PPThe.B -voption outputs all functions and/or lines even when the percentageof time spent in them is zero..PPThe.B -moption lists the module names which are to be profiled. If none are given, all themodules loaded by the kernel will be profiled. The name may be the actual name ofthe module or its path name..PPThe.B -eoption profiles the module that is loaded first in any following command. In this casethere is no need to give a.B -moption as this is added automatically..PPThe.B -soption sets the sample interval.I rateand is expressed in ms. The default is 100 ms..PPAny remaining arguments are assumed tospecify a command and set of arguments to the command. If this is the case,.B profwill automatically start profiling, run the command to completion and thenstop profiling before showing the profile statistics..PP.B Profdisplays the profile statistics (unless the.B -boption is being used) according to the output format required..PP.SH EXAMPLE.EXTo profile a particular command	prof /dis/math/parts 10000	wm/prof /dis/math/parts 10000To profile the same command but restrict attention to its own module (Partitions).	prof -m Partitions /dis/math/parts 10000	wm/prof -m Partitions /dis/math/parts 10000A shorter version of the above	prof -e /dis/math/parts 10000	wm/prof -e /dis/math/parts 10000To profile interactively	prof -b -m Partitions -s 10	/dis/math/parts 10000	prof -f -l -n .EE.PPNote that the output format options (.B -f, .B -l, .B -n, .B -v) are ignored when .B -bis present..SH SOURCE.B /appl/cmd/prof.b.PP.B /appl/wm/prof.b.SH SEE ALSO.IR cprof (1),.IR mprof (1),.IR wm-cprof (1),.IR wm-mprof (1),.IR prof (2),.IR prof (3).SH BUGS.I Profcannot profile compiled limbo programs.
