Greetings,
Welcome to the TCG Continuous Benchmarking GSoC project!
This is the first report in a series that will be posted here on the
mailing list as part of the project.
During the project, multiple Linux profiling tools will be used.
These tools will help you profile your different QEMU execution
scenarios, and locate performance bottlenecks as well as performance
regression problems.
To provide you with a better understanding of these tools, this report
presents two of them - Perf and Callgrind.
It starts with measuring the basic performance metrics when running
a program using both tools, then it proceeds to calculating the top 25
most executed functions in QEMU.
To dissect the output of each of the two tools, a separate section
for comparing the output results is presented which focuses on how
these results apply to QEMU.
Finally, a stability test is devised that compares how the output
of the two tools differ with each subsequent invocation of QEMU.
For easier accessibility, all reports will be hosted on a dedicated
website:
