Package: wnpp Version: N/A; reported 2002-03-22 Severity: wishlist * Package name : oprofile Version : 0.1 Upstream Author : John Levon <[EMAIL PROTECTED]> * URL : http://oprofile.sourceforge.net * License : GPL Description : OProfile is a system-wide profiler for Linux x86 systems, capable of profiling all running code at low overhead.
Features Unobtrusive No special recompilations, wrapper libraries or the like are necessary. Even debug symbols (-g option to gcc) are not necessary unless you want to produce annotated source. No kernel patch is needed - just insert the module. System-wide profiling All code running on the system is profiled, enabling analysis of system performance. Performance counter support Enables collection of various low-level data, and assocation with particular sections of code. Low overhead OProfile has a typical overhead of 3-8%, dependent on sampling frequency and workload. Post-profile analysis Profile data can be produced on the function-level or instruction-level detail. Source trees annotated with profile information can be created. A hit list of applications and functions that take the most time across the whole system can be produced. System support OProfile works across a range of x86 CPUs, including the Athlon/Duron range. Full support for Pentium IV is not yet present. OProfile will work against almost any 2.2 and 2.4 kernel, and works on both UP and SMP systems. -- System Information Debian Release: unstable Architecture: i386 Kernel: Linux mizar 2.4.18 #1 Tue Mar 12 08:58:12 EST 2002 i686 Locale: LANG=en_US, LC_CTYPE=en_US -- - mdz
