Chrome(mium) cahche on ramdisk

chrome-cahche-on-ramdisk.mkd

Google Chrome cache to ramdisk optimization

performance improvements when running within slow I/O device

• if install to flash-drive(aka pen-drive, flash-memory)
• e.g. Linux working on flash-drive

command line option

add option to launching menu like this;

google-chrome %U --disk-cache-dir="/ramdisk/cache/google-chrome"

option --disk-cache-dir same in use on terminal and run-dialog

👍

• easy
• auto create directories
• like mkdir -p

👎

• don't apply globally
• e.g. invoke by somebody application
• some cache-files on default cache dir

symbolic link

cache dir makes up to symlink, like this;

DEF_CACHE=~/.cache/google-chrome
RAM_CACHE=/ramdisk/cache/google-chrome

rm -rf "$DEF_CACHE" # remove default cache dir
mkdir -p "$RAM_CACHE"
ln -s "$RAM_CACHE" "$DEF_CACHE"

so symlink like this;

knoppix@Microknoppix:~$ ls -l ~/.cache/google-chrome 
lrwxrwxrwx 1 knoppix knoppix 28  6月 10 06:51 /home/knoppix/.cache/google-chrome -> /ramdisk/cache/google-chrome
knoppix@Microknoppix:~$ 

👍

• apply in globally
• all caches to ram

👎

• little bit technical
• not create child directories
• must be exist dest-dir
• i.e. /ramdisk/ has not child dir, cache-files has gone(or nothing)

if change to useful, simplify symlink like this;

$ ln -s /ramdisk ~/.cache/google-chrome

mount point /ramdisk absolutely exist, but might be collision to other application caches
