You have a lot of logs there. Try to process older in few steps, by month/year or something like.

Another option is to reduce CPU number.

[`max_procs`](https://www.elastic.co/docs/reference/beats/filebeat/configuration-general-options#_max_procs)

_Sets the maximum number of CPUs that can be executing simultaneously. The default is the number of logical CPUs available in the system._

If the CPU load is still high, after changing max\_procs, read [this](https://discuss.elastic.co/t/limiting-number-of-cpu-usage-in-filebeat/161490) topic.
