We experience a huge performance hit after job rename for 30 minutes. The Jenkins is unresponsive and unusable from user side. Loading of any Jenkins page took 4-5 minutes.

Is it possible: 

 - Option1 - to lower the priority of the thread responsible for the search and replace of the old job name with the new one in the old builds

 - Option2 - to implement an additional group with permissions to rename jobs

 - Option3 - to add an option to disable search and replace the old job name with the new job name in all older jobs builds (different than the one which we rename)

Please let me know if there is already plan for fixing this issue?
