If anyone else lands here and wonders what the status is in Ubuntu 13.10:
Bug is fixed in kernel 3.11.0-17-generic 3.11.0-17.30 for me. I downloaded and installed it from the Canonical Kernel team PPA:
https://launchpad.net/~canonical-kernel-team/+archive/ppa

I guess it will appear in -proposed eventually ..

Title:
  8086:422c [Dell Latitude E6510] iwlwifi: tx speed regression with
  kernel 3.11.0-15-generic

Status in “linux” package in Ubuntu:
  Fix Released

Bug description:
  Kernel 3.11.0-15-generic appears to regress iwlwifi performance
  significantly. I get about 400-500KiB/s sustained transfer rate with
  3.11.0-15-generic, while speed is over 7MiB/s with either
  3.11.0-12-generic or mainline kernel v3.11.10.3-saucy (same access
  point).
