http://www.cyberciti.biz/tips/what-is-devshm-and-its-practical-usage.html
In this example, remount /dev/shm with 8G size as follows:
# mount -o remount,size=8G /dev/shm
To be frank, if you have more than 2GB RAM + multiple Virtual machines,
this hack always improves performance. In this example, you will give you
tmpfs instance on /disk2/tmpfs which can allocate 5GB RAM/SWAP in 5K inodes
and it is only accessible by root:
# mount -t tmpfs -o size=5G,nr_inodes=5k,mode=700 tmpfs /disk2/tmpfs
Where,
-o opt1,opt2 : Pass various options with a -o flag followed by a comma
separated string of options. In this examples, I used the
following options:
remount : Attempt to remount an already-mounted filesystem. In this
example, remount the system and increase its size.
size=8G or size=5G : Override default maximum size of the
/dev/shm filesystem. he size is given in bytes,
and rounded up to entire pages. The default is half
of the memory. The size parameter also accepts a
suffix % to limit this tmpfs instance to that
percentage of your pysical RAM: the default, when
neither size nor nr_blocks is specified, is
size=50%. In this example it is set to 8GiB or 5GiB.
The tmpfs mount options for sizing ( size,
nr_blocks, and nr_inodes) accept a suffix k, m or
g for Ki, Mi, Gi (binary kilo, mega and giga) and
can be changed on remount.
nr_inodes=5k : The maximum number of inodes for this instance. The
default is half of the number of your physical RAM pages,
or (on a machine with highmem) the number of lowmem RAM
pages, whichever is the lower.
mode=700 : Set initial permissions of the root directory.
tmpfs : Tmpfs is a file system which keeps all files in virtual memory.

mount -t [TYPE] -o size=[SIZE],opt2=[opt2],opt3=[opt3] [FSTYPE] [MOUNTPOINT]
Substitute the following attirbutes for your own values:
[TYPE] is the type of RAM disk to use; either tmpfs or ramfs.
[SIZE] is the size to use for the file system. Remember that ramfs does not
have a physical limit and is specified as a starting size.
[FSTYPE] is the type of RAM disk to use; either tmpfs, ramfs, ext4, etc.
Example:
mount -t tmpfs -o size=512m tmpfs /mnt/ramdisk

http://www.cyberciti.biz/tips/what-is-devshm-and-its-practical-usage.html
In this example, remount /dev/shm with 8G size as follows:
# mount -o remount,size=8G /dev/shm
To be frank, if you have more than 2GB RAM + multiple Virtual machines,
this hack always improves performance. In this example, you will give you
tmpfs instance on /disk2/tmpfs which can allocate 5GB RAM/SWAP in 5K inodes
and it is only accessible by root:
# mount -t tmpfs -o size=5G,nr_inodes=5k,mode=700 tmpfs /disk2/tmpfs
Where,
-o opt1,opt2 : Pass various options with a -o flag followed by a comma
separated string of options. In this examples, I used the
following options:
remount : Attempt to remount an already-mounted filesystem. In this
example, remount the system and increase its size.
size=8G or size=5G : Override default maximum size of the
/dev/shm filesystem. he size is given in bytes,
and rounded up to entire pages. The default is half
of the memory. The size parameter also accepts a
suffix % to limit this tmpfs instance to that
percentage of your pysical RAM: the default, when
neither size nor nr_blocks is specified, is
size=50%. In this example it is set to 8GiB or 5GiB.
The tmpfs mount options for sizing ( size,
nr_blocks, and nr_inodes) accept a suffix k, m or
g for Ki, Mi, Gi (binary kilo, mega and giga) and
can be changed on remount.
nr_inodes=5k : The maximum number of inodes for this instance. The
default is half of the number of your physical RAM pages,
or (on a machine with highmem) the number of lowmem RAM
pages, whichever is the lower.
mode=700 : Set initial permissions of the root directory.
tmpfs : Tmpfs is a file system which keeps all files in virtual memory.

[SIZE] is the size to use for the file system. Remember that ramfs does not
