VM tweaks (explained below)

VM Tweaks

dirty ratio and dirty background ratio 1 & 2

This controls how often the kernel writes data to "disk" (in our case the internal microSD system card, not the removable microSD card). When your apps write data to disk, Linux actually doesn't write the data out to the disk right away, it actually writes the stuff to system memory and the kernel handles when and how the data is actually going to be flushed to the disk. These values represent a percentage, the higher the percentage, the longer it waits to flush, the lower the percentage, the more often flushes will occur. Now remember, we are dealing with solid state storage, not the traditional disk platter and spindle. So we are actually able to delay flushes a little longer with solid state versus a traditional hard drive disk.

dirty_expire_centisecs

How old "dirty" data should be before the kernel considers it old enough to be written to disk. It is expressed in 100ths of a second.

dirty_writeback_centisecs

This is the interval of when the writeback daemons periodically wake up and write "old" data out to disk. It is expressed in 100ths of a second.

min free kbytes

This is used to force the Linux VM to keep a minimum number of kilobytes free. The VM uses this number to compute a pages_min value for each lowmem zone in the system. Each lowmem zone gets a number of reserved free pages based proportionally on its size. Default is 2048kb.

overcommit_memory

This controls overcommit of system memory, possibly allowing processes to allocate (but not use) more memory than is actually available.

0 - Heuristic overcommit handling. Obvious overcommits of address space are refused. Used for a typical system. It ensures a seriously wild allocation fails while allowing overcommit to reduce swap usage. root is allowed to allocate slighly more memory in this mode. This is the default.

1 - Always overcommit. Appropriate for some scientific applications.

2 - Don't overcommit. The total address space commit for the system is not permitted to exceed swap plus a configurable percentage (default is 50) of physical RAM. Depending on the percentage you use, in most situations this means a process will not be killed while attempting to use already-allocated memory but will receive errors on memory allocation as appropriate.

Swappiness

A property for the Linux kernel that changes the balance between swapping out runtime memory, as opposed to dropping pages from the system page cache. Swappiness can be set to values between 0 and 100 inclusive. A low value means the kernel will try to avoid swapping as much as possible where a higher value instead will make the kernel aggressively try to use swap space.

VFS Cache Pressure

File system cache (dentry/inode) is really more important than the block cache above in dirty ratio and dirty background ratio, so we really want the kernel to use up much more of the RAM for file system cache, this will increas the performance of the system without sacrificing performance at the application level. The default value is 100, as a percentage, and what you want to do is lower the value to tell the kernel to favor the file system cache and not drop them aggressively.

8/ Enable / Disable Quick Key Reset
