Sorry, I thought it was obvious. Paste before the figures those lines then:
CPU: Core 2, speed 3159.01 MHz (estimated)
Counted CPU_CLK_UNHALTED events (Clock cycles when not halted) with a unit mask
of 0x00 (Unhalted core cycles) count 100000
samples % image name symbol name
Anyway, those figures were wrong. For some reason, I can't force oprofile to
include the time taken in external symbols, in particular SDL. If we list 'per
module', we get:
samples| %|
208215 26.3824 libSDL-1.2.so.0.11.1
114896 14.5582 no-vmlinux
82889 10.5026 nvidia_drv.so
48369 6.1287 wormux
So, 20% of 6% reduced by half, won't improve much anything. Even more since
this is for x86/X11 and I can't get any figure for the actual target.
Anyway, the top five within wormux are now:
samples % image name symbol name
9170 18.9584 wormux GetObjectAt(Vector2<int> const&)
7839 16.2067 wormux Surface::MergeSurface(Surface&,
Vector2<int> const&)
1979 4.0915 wormux
PhysicalObj::CollidedObjectXY(Vector2<int> const&) const
1768 3.6552 wormux fixedpoint::fixsqrt16(long long)
1751 3.6201 wormux Member::ApplyMovement(member_mvt
const&, std::vector<c_junction*, std::allocator<c_junction*> >&)
GetObjectAt is here because I let 2 AI teams play against each other.
