Re: Timing comparisons for multi-kprobe feature


Here's the result on the 4 way 700mhz Pentium 3

(All values in microseconds)

       Vanilla        Single        Multiple
       (2.6.12-rc2)    Interface    Interfaces
------------------------------------------------------------
kprobe        1.155      1.195       1.2
jprobe        1.934      1.987       1.967
kprobe_multi    NA       1.478       1.498

Thanks, Hien.

Hi,

Here is the result of the tests I carried out to determine the cost
of the multiple-kprobes feature. All tests were carried out on a
uni PIII running at 732MHz.

I used Will's timing_kprobe and kprobe_multi modules on linux-2.6.12-rc2
for the tests.

(All values in microseconds)

        Vanilla        Single        Multiple
        (2.6.12-rc2)    Interface    Interfaces
------------------------------------------------------------
kprobe        1.124        1.149        1.149
jprobe        1.891        1.885        1.885
kprobe_multi    NA        1.306        1.387

Note:
- Single Interface => linux-2.6.12-rc2 + take3 patch
- Multiple Interfaces => linux-2.6.12-rc2 + take4 patch
- kprobe_multi => averaged values with Will's kprobe_multi testcase

Thanks,
Ananth
