I used LTT once to help investigate system startup performance issues on
a Linux-based cell phone prototype. One thing that might be different
from most LTT user's experiences is that it was somebody else's
software, for which I did not have the source. This might help
illustrate ways in which system administrators can analyze systems for
improvements, rather than describing a more typical development
scenario, although this does describe the development phase of a system.
LTT helped quantify the performance impacts of various system activities
that might be best minimized (including unneeded system startup scripts
and the importance of using shell builtins, as well as suggesting
improvements that might be obtained through use of prelinking shared
libraries), point out various repeated operations that could probably be
consolidated (such as file access, process scheduling, and X
client/server communication), and rule out low memory or the need for
swapping as a cause of performance problems at that phase of system
operation.
A great tool, highly recommended.
