Sets the number of hardware network events to handle before performing other work. This is a hint for internal tuning, and the actual number handled might differ. The value chosen represents a trade-off: Larger values increase batching (which typically improves efficiency) but can also increase the working set size (which harms cache efficiency). When EF_POLL_IN_KERNEL is set (either explicitly or implicitly) then the default value is 192, to increase batching efficiency.
