Status: Closed |
A PERFORMANCE PROBLEM HAPPENS WHILE -PERFSTAT_MEMORY_TOTAL CALLS VMGETINFO |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
A big performance difference is seen with the call
perfstat_memory total.
In perfstat_memory_total, it calls vmgetinfo() with VMINFO as
following:
vmgetinfo(&vminfo, VMINFO, sizeof(struct vminfo))
However, it can call vmgetinfo with VMINFO_ABRIDGED directly
instead of perfstat_memory_total as following:
vmgetinfo(&vminfo, VMINFO_ABRIDGED, sizeof(struct vminfo)) |
