It is normal—and expected—for the Hyperscience application to consume 100% of its CPUs' resources. In v28.0.8+, v28.2.1+, and v30 and later, you can limit the percentage of CPU resources it consumes by setting the HS_MAX_CPU_PERC variable in your instance's ".env" file:
HS_MAX_CPU_PERC=<percentage expressed as an integer less than 100>
After setting this variable, you'll need to apply your changes. To do so, run the "apply-system-settings" command on each machine running the application:
sudo ./run.sh apply-system-settings
