FTrace parsing slow on large traces

[bjackman]

The example trace (220Mb) used by Lisa's Trappy tutorial notebook takes 15-20 seconds to parse on my machine (Xeon Sandy Bridge, E5-1660). That seems like it might be a regression. Should figure out what's taking up all the time.

Events parsed are:

    "sched_switch",
    "sched_wakeup",
    "sched_contrib_scale_f",
    "sched_load_avg_cpu",
    "sched_load_avg_task",
    "sched_tune_tasks_update",
    "sched_boost_cpu",
    "sched_boost_task",
    "sched_energy_diff",
    "sched_overutilized",
    "cpu_frequency",
    "cpu_capacity"

Closing this as I cant repro any more :confused:

Maybe my computer was tired
