dtrace overhead and proper measuring technique
I''m trying to time a function within Firefoxwith a pid$target probe
[2]. e.g
dtrace -Zqw -x dynvarsize=64m -x evaltime=preinit -p 13954 -s menu-
construct.d -s sigcont.d
elapsed: 12.7942481ms
cpu : 7.7911194ms
count : 40 times
I''m also measuring Firefox startup time by running it arguments like

[PATCH 0/7] x86 paravirtualization infrastructure
The following patches introduce the core infrastructure needed to
paravirtualize the 32-bit x86 Linux kernel. This is done by moving
virtualization sensitive insn's or code paths to a function table,
paravirt_ops. This structure can be populated with hypervisor specific
calls or native stubs and currently support running on bare metal, VMI,
Xen, or Lhype. These patches apply to

[RFC PATCH 00/33] Xen i386 paravirtualization support
Unlike full virtualization in which the virtual machine provides
the same platform interface as running natively on the hardware,
paravirtualization requires modification to the guest operating system
to work with the platform interface provided by the hypervisor.
Xen was designed with performance in mind. Calls to the hypervisor
are minimized, batched if necessary, and non-critical codepaths

[PATCH 00/28] Updates for firstfloor paravirt-ops patches
Hi Andi,
This is a set of updates for the firstfloor patch queue.
Quick rundown:
revert-mm-x86_64-mm-account-for-module-percpu-space-separately-from-kernel-percpu.patch
separate-module-percpu-space.patch
Update the module percpu accounting patch
fix-ff-allow-percpu-variables-to-be-page-aligned.patch
Make sure the percpu memory allocation is page-aligned
