    Description

      Steps to reproduce:
      Enable profiling:

      DCget_host_count() locked:1 busy:16.226569 wait:0.000050
      DCget_required_performance() locked:1 busy:16.575361 wait:0.000052
      DCget_item_queue() locked:3 busy:4.984448 wait:0.00033
      DCget_item_queue() locked:2 busy:3.342432 wait:0.000428
      DCget_item_queue() locked:1 busy:1.666648 wait:0.000215
      

      Probably this items are involved:

      • zabbix["queue",<from>,<to>]
      • zabbix["hosts"]
      • zabbix["requiredperformance"]

      Please remove heavy locking to get such stats.
