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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
