Description
On a customer site, we have seen high CPU utilization in the 85% or more range with multiple cores (more than 20 cores). ESM will spin up a sub importer per core, so there could be 20+ sub importers in this scenario. Each using CPU, the total can be very high. On newer windows operating systems, this seems to balance correctly and not using high CPU.
If a customer is seeing this, you can configure the ESM importer to spin up a lower number of sub importers. By setting the _ESM_NUM_IMPORTERS=X where X is the number you want to use, in system environment variables, you can limit the number it spins up. Thus reducing the CPU load.
