Profiling the FreeBSD kernel boot
semanticscholar(2017)
摘要
We describe work we have done to profile the FreeBSD kernel boot — both adding instrumentation to the kernel to collect data while the system is booting, and converting the resulting timestamp records into a graphical visualization of where time is spent in the boot process. We show results from two systems and highlight some places where it is clear that the performance of the FreeBSD boot process can be improved.
