27 Just a side-note to say that I've got just this package running and
28 working with -fstack-protector.
29
30 I can also add that I've been doing x86 stable tracking with
31 -fstack-protector for almost a year now, sometimes things break, but
32 bugreports have been filed and things have been very smooth the last few
33 months.
34
35
36 +1 for recommending it to default.
37
38 Can somone take the time to benchmark this properly though? we rather
39 shouldn't have many "oh this sucks 15% cpu" rumours without substance.
40 both string and integer, small and large software.
41
42 Some of the more interesting parts would be fex. python performance and
43 performance of python apps.
