    Description

      The upstream GPerftools master has merged a commit adding a new MarkThreadTemporarilyIdle function that may offer us improved performance over our current practice of calling MarkThreaIdle followed immediately by MarkThreadBusy.

      We should benchmark the following configurations and understand the effects:

      • Master, built against the system allocator
      • Master, built against the vendored tcmalloc, with the MarkThreadIdle/MarkThreadBusy subsystem disabled
      • Master, built against the vendored tcmalloc, using the current MarkThreadIdle/MarkThreadBusy subsystem.
      • Master, built against the gperftools master, with the MarkThreadIdle/MarkThreadBusy subsystem disabled
      • Master, built against the gperftools master, using the current MarkThreadIdle/MarkThreadBusy subsystem
      • Master, built against the gperftools master, using the new MarkThreadTemporarilyIdle API.
