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
