Parallel GETNEXT

Perform SNMP v2c GETNEXT requests to iterate through whole MIB with concurrency of 4 maintaining single client session per thread/coroutine. Use SHA-1 hasing and AES-128 encryption. This test evaluates:

  • The efficiency of the network stack.
  • The efficiency of BER encoder and decoder.
  • The efficiency of the BER-to-Python data types mapping.
  • Granularity of the internal locks.
  • Ability to release GIL when runnning native code.

Look at the source code for details.

Notes

  • easysnmp doesn't supports async mode
