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 rhodecode.ini file would benefit from this.

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 operating system instructions. The expected performance benefit is approximately 5%. You should ensure you allocate an adequate amount of memory depending on your available resources.

# 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

In order to make this change permanent it’s recommend to set it as /etc/fstab entry.

tmpfs   /home/user/.rccontrol/enterprise-1/data tmpfs   nodev,nosuid,noexec,nodiratime,size=2G   0 0

Move tmp to TMPFS#

RhodeCode Enterprise components heavily use the /tmp folder, so moving your /tmp folder into to a RAM-based TMPS can lead to a noticeable performance boost.

# mount tmp to memory with 2GB limit and 1777 write permissions
mount -t tmpfs -o size=2G,mode=1777 tmpfs /tmp
