Susan Hinrichs reassigned TS-1775:
----------------------------------
Assignee: Susan Hinrichs (was: James Peach)
> Cleanup of ink_hrtime.{cc,h}
> ----------------------------
>
> Key: TS-1775
> URL: https://issues.apache.org/jira/browse/TS-1775
> Project: Traffic Server
> Issue Type: Improvement
> Reporter: Leif Hedstrom
> Assignee: Susan Hinrichs
> Labels: newbie
> Fix For: 6.0.0
>
>
> A few things comes to mind:
> 1) Why do we have a NEED_HRTIME define? It's always on as far as I can tell,
> and I can't imagine there's a reason to not have it on (it'd completely break
> like everything, in fact it would fail to compile since gethrtime() doesn't
> exist?).
> 2) We should eliminate the USE_TIME_STAMP_COUNTER_HRTIME define, and the code
> that implements our own TSC code. Modern Unix flavors implements this already
> in various way (e.g. glibc's gettimeofday() wrapper has a TSC user space
> implementation).
> 3) On FreeBSD, jpeach points out that CLOCK_REALTIME is probably not the
> optimal way to use clock_gettime(). He suggest using CLOCK_REALTIME_FAST or
> CLOCK_MONOTONIC_FAST which is similar to the optimizations done with TSC for
> gettimeofday() on linux.
