  * Large pages need a properly set up OS. It can be difficult if you are not used to systems administration,
  * but the performance results are worth the trouble - you will get around 20% boost. Slow memory mode is
  * meant as a backup, you won't get stellar results there. If you are running into trouble, especially
- * on Windows, please read the common issues in the README.
- *
- * By default we will try to allocate large pages. This means you need to "Run As Administrator" on Windows.
- * You need to edit your system's group policies to enable locking large pages. Here are the steps from MSDN
- *
- * 1. On the Start menu, click Run. In the Open box, type gpedit.msc.
- * 2. On the Local Group Policy Editor console, expand Computer Configuration, and then expand Windows Settings.
- * 3. Expand Security Settings, and then expand Local Policies.
- * 4. Select the User Rights Assignment folder.
- * 5. The policies will be displayed in the details pane.
- * 6. In the pane, double-click Lock pages in memory.
- * 7. In the Local Security Setting – Lock pages in memory dialog box, click Add User or Group.
- * 8. In the Select Users, Service Accounts, or Groups dialog box, add an account that you will run the miner on
- * 9. Reboot for change to take effect.

- * Windows also tends to fragment memory a lot. If you are running on a system with 4-8GB of RAM you might need
- * to switch off all the auto-start applications and reboot to have a large enough chunk of contiguous memory.
- *
- * On Linux you will need to configure large page support "sudo sysctl -w vm.nr_hugepages=128" and increase your
- * ulimit -l. To do do this you need to add following lines to /etc/security/limits.conf - "* soft memlock 262144"
- * and "* hard memlock 262144". You can also do it Windows-style and simply run-as-root, but this is NOT
- * recommended for security reasons.
- *
- * Memory locking means that the kernel can't swap out the page to disk - something that is unlikely to happen on a
- * command line system that isn't starved of memory. I haven't observed any difference on a CLI Linux system between
- * locked and unlocked memory. If that is your setup see option "no_mlck".
