LTProf

LTProf is a small but powerful code profiler tool for VC++, CBuilder, Delphi and VB applications. Although small, it has a combination of features difficult to find in even the most expensive tools available today:

Line level resolution
One of the best features of LTProf. Most profilers have a function-level resolution, that is, they can display a list of functions and the time spent in each one. LTProf goes further and displays graphically, on the source file, time spent by each line of code, relative to the function it belongs to. Thus if you have a long algorithm you can see which parts of it are the most time consuming.

No instrumentation, no rebuild, no time wasted
Unlike most profilers on the market LTProf does not require a rebuild or an instrumentation step. The normal build of your application can be profiled at any stage in its development, without any other adjustments.

Profiled program runs at its normal speed
Instrumented programs have additional code inserted in every function to measure the time spent, which greatly reduces the program`s speed because some of the instrumented functions are called very often. It is not uncommon that slow programs become completely unusable after instrumentation.
LTProf does not change your application in any way, which means it can run at its normal speed, making your life a lot easier. The amount of processor time consumed by LTProf itself can be adjusted by setting the sampling resolution.

Profile VC++, CBuilder, Delphi and Visual Basic code
as well as any application that stores debug information in PDB/TDS files. LTProf is not language-oriented and it can analyze any program as long as it contains debug information in PDB/TDS files. It can do so even in cross-language applications, for example an EXE written in C++ that uses VB components.
