Hello :)
I have tried all the demos from the SFML book, a few existing projects, and some of my own SFML code, in all of them I experience the following:
About 2-3s after I start any SFML program, the window seems to freeze for about 0.5-1s, then things continue normally (no more freezes after that). Audio is not affected, only rendering.
The machine is an Intel i7-3770T with on-chip HD2000 (?) graphics card. System is Arch Linux, 64bit, 3.14.4.
SFML is git as of today (same problem on 2.1 release).
This does not happen on any other library or game I've tried so far.
Is there a way to help debug this? Has this happened to anyone else?
Thanks for any help!

What graphics driver are you using?
Do you run it in release mode?
There are CPU ans GPU profilers, but not sure what exists on Arch.

glxinfo says
direct rendering: Yes
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Ivybridge Desktop
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.1.4
I have Option "AccelMethod" "uxa" set for X11 also. I haven't enabled any debugging, that shouldn't be a problem. Also, this never happens with any other library or framework, which makes me suspect SFML does something my driver doesn't like :(

Doesn't quite answer if you're running a debug or a release build. ;)

(That's actually Intel HD 4000 graphics)

if you mean SFML, release.
