* Number of threads. You can configure them below. Cryptonight uses 2MB of memory, so the optimal setting
* here is the size of your L3 cache divided by 2. Intel mid-to-high end desktop processors have 2MB of L3
* cache per physical core. Low end cpus can have 1.5 or 1 MB while Xeons can have 2, 2.5 or 3MB per core.

* the maximum performance.
*
* no_prefetch - This mode meant for large pages only. It will generate an error if running on slow memory
* Some sytems can gain up to extra 5% here, but sometimes it will have no difference or make

* systems it is better to assign threads to physical cores. On Windows this usually means selecting
* even or odd numbered cpu numbers. For Linux it will be usually the lower CPU numbers, so for a 4

/*
* LARGE PAGE SUPPORT
* Lare pages need a properly set up OS. It can be difficult if you are not used to systems administation,
* but the performace 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 unlikey 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".
*/

* no_mlck - This option is only relevant on Linux, where we can use large pages without locking memory.
* It will never use slow memory, but it won't attempt to mlock
* never - If we fail to allocate large pages we will print an error and exit.

* long timeouts mean that we waste hashes on potentially stale jobs. Connection report will tell you how long the
* server usually takes to process our calls.
*
* call_timeout - How long should we wait for a response from the server before we assume it is dead and drop the connection.
* retry_time - How long should we wait before another connection attempt.
* Both values are in seconds.
* giveup_limit - Limit how many times we try to reconnect to the pool. Zero means no limit. Note that stak miners
* don't mine while the connection is lost, so your computer's power usage goes down to idle.

* Press 'h' (hashrate), 'r' (results) or 'c' (connection) to print reports.
