Put this into your ~/.gdbinit

define timeme
    python import time
    python starttime=time.time()
    next
    python print("Previous takes: " + (str)(time.time()-starttime) + "s")
end
document timeme
    Measure executing time of next function
    Usage: timeme or ti
end

type timeme or ti when you want to measure the time of next function.
