>I will check the Declaration you provided. As for the Coverage Profiler, I use often to validate the code coverage. The timing portion can be helpful, but does not provide real-time numbers.

My guess is it does provide real time numbers, but they are NOT really comparable to runtimes without coverage, as the writing out severly thrashes performance of single lines. With those timers you can get much better picture of runtimes of small code stretches - but to really effective you must write the timing fwk in C (did that once after piping counters into vfp array at first). With Queryperf you are miles ahead of Gettickcount, but the last mile for short calls run a few million times is better in C.
Just store API results first in C memory space, then after measurement analyze data structure.

Gettickcount usually is good enough for SQL queries, xBase calc calls and finding unoptmised locates.
But there already is the optimizing output ;-)
