Public bug reported: The debug tracepoint in Dnsmasq._output_hosts_file is extraneous and causes unnecessary performance overhead due to string formating when creating lots (> 1000) ports at one time.
The trace point is unnecessary since the data is being written to disk and the file can be examined in a worst case scenario. The added performance overhead is an order of magnitude in difference (~.5 seconds versus ~.05 seconds at 1500 ports). ** Affects: neutron Importance: Undecided Assignee: Billy Olsen (billy-olsen) Status: In Progress ** Changed in: neutron Assignee: (unassigned) => Billy Olsen (billy-olsen) ** Changed in: neutron Status: New => In Progress -- You received this bug notification because you are a member of Yahoo!
