Mount Cache Folders To Memory
-----------------------------
To increase the performance of folders containing cache data, you can mount
them to memory. The following folders specified in the :file:`rhodecode.ini`
file would benefit from this.
.. code-block:: ini
cache_dir = %(here)s/data
search.location = %(here)s/data/index
Use the following Ubuntu example to mount these to memory, or see your
particular |os| instructions. The expected performance benefit is
approximately 5%. You should ensure you allocate an adequate amount of memory
depending on your available resources.
.. code-block:: bash
# mount to memory with 2GB limit and 755 write permissions
mount -t tmpfs -o size=2G,mode=0755 tmpfs /home/user/.rccontrol/enterprise-1/data
mount -t tmpfs -o size=2G,mode=0755 tmpfs /home/user/.rccontrol/enterprise-1/data/index
.. _move-tmp:
docs: added example how to make tmpfs changes permanent
r2159
In order to make this change permanent it's recommend to set it as /etc/fstab
entry.
.. code-block:: bash
tmpfs /home/user/.rccontrol/enterprise-1/data tmpfs nodev,nosuid,noexec,nodiratime,size=2G 0 0

r1 Move ``tmp`` to TMPFS
---------------------
|RCE| components heavily use the :file:`/tmp` folder, so moving your
:file:`/tmp` folder into to a RAM-based TMPS can lead to a noticeable
performance boost.
.. code-block:: bash
Suggest different permissions for tmpfs-mounted /tmp
r1278 # mount tmp to memory with 2GB limit and 1777 write permissions
mount -t tmpfs -o size=2G,mode=1777 tmpfs /tmp
