Klaus Ma commented on MESOS-5700:
---------------------------------
Just did a profiling for Resources class based on the benchmark, please refer
to the attachment for the detail. Here's suggestion to improve the performance:
1. In reservation.perf.log, it shows {{operator!=(string, string)}} in
{{addable/subtractable}} is the heavy function; so I'm thinking to
* Make name of Resource to be enum instread of string (as we discussed in
the doc)
* Introduce roleId (uint64_t), similar to uid in Linux; {{roleId}} is used
within Mesos master/agent
2. In port.perf.log, it shows {{ranges validation}} is the heavy function; no
conclusion for now, but it's better to refine {{Resource::validate}}:
* role validation is not necessary in every operator/loop
* ranges validation maybe not necessary in every operator/loop,
{{coalesce}} may handle it (investigating)
