[dpdk-dev] [PATCH] test: reduce duration for timer autotest

[Jananee Parthasarathy]

Reduced the test duration of timer_autotest.
The number of iterations was very large to test the timer functionality.
Although the method to identify random timers can be different,
many iterations would be needed for stress or performance test only.

Just reduce the iteration to some number, instead of using macro NB_STRESS2_TIMERS, which seem to be specific for number of timers.

(Or) can this test be considered as perf ? and ignore above changes.? 

Any one any comments?

Thanks,
Reshma

NB_STRESS2_TIMERS is used for all iterations in the test and timer structure is allocated NB_STRESS2_TIMERS only, hence used the same.

This seems to be stress test so better to be considered as perf test and no changes are required.

Please let us know about it.

I am fine to consider this as perf test category.

When test was ran with reasonable number of lcores ex: 16 the test time is within targeted value of 10sec.
Without specifying the core limit test will run on all available cores and can take longer time. 

So this patch can be Nacked now as expected timings are achieved by limiting the number of cores.
