@jasnell I haven't specifically tested the performance, but I would guess it should still see an increase.

Why the dont-land-on-v4.x?

The don't land on v4 is largely precautionary. If it can be shown to be safe we can pick it back

Notable changes

* performance: The performance of several APIs has been improved.
  - `Buffer.compare()` is up to 35% faster on average. (Brian White)
    #10927
  - `buffer.toJSON()` is up to 2859% faster on average. (Brian White)
    #10895
  - `fs.*statSync()` functions are now up to 9.3% faster on average.
    (Brian White) #11522
  - `os.loadavg` is up to 151% faster. (Brian White)
    #11516
  - `process.memoryUsage()` is up to 34% faster. (Brian White)
    #11497
  - `querystring.unescape()` for `Buffer`s is 15% faster on average.
    (Brian White) #10837
  - `querystring.stringify()` is up to 7.8% faster on average.
    (Brian White) #10852
  - `querystring.parse()` is up to 21% faster on average. (Brian White)
    #10874

* IPC:
  - Batched writes have been enabled for process IPC on platforms that
    support Unix Domain Sockets. (Alexey Orlenko)
    #10677
  - Performance gains may be up to 40% for some workloads.

* child_process:
  - `spawnSync` now returns a null `status` when child is terminated by
    a signal. (cjihrig) #11288
  - This fixes the behavior to act like `spawn()` does.

  - Control characters are now always rejected when using
    `http.request()`. (Ben Noordhuis)
    #8923
  - Debug messages have been added for cases when headers contain
    invalid values. (Evan Lucas)
    #9195

* node:
  - Heap statistics now support values larger than 4GB. (Ben Noordhuis)
    #10186
