cdropp

ram cache dropper for linux

---

I recently decided to play gta5 and found that after about 40-50 minutes the game crashes with the error "Out-Of-Memory". Although availible ram still more than 5gb. After a while I realized that gta is overloading ram cache and kernel has no time to take availible memory from other applications which leads to crashes.

Since I'm a bit of a developer I decided to write a daemon which will clear the cache during the game.

How to Install?

1) install go

2) clone repo

git clone https://github.com/ssleert/cdropp.go

3) make

make build
sudo make install

How to uninstall?

sudo make uninstall

or

sudo rm /usr/local/bin/cdropp

How to use?

Check version.

~> cdropp -v
cdropp - 0.0.1

Get help message.

~> cdropp -h
cdropp - simple deamon for dropping caches in ram
 -d --daemon  | start main loop
 -c --check   | check current ram usage
 -v --version | print program version
 -h --help    | print help message

Check ram stats.

~> cdropp -c
ram info:
 total     - 15883 mb
 free      - 3364 mb
 availible - 4252 mb

Start in deamon mode.

~> cdropp -d # with debug=1
2023/01/06 18:25:44 cache dropped | panic: 0
2023/01/06 18:25:44 cache checked | panic: 0
2023/01/06 18:25:44 cache dropped | panic: 0
2023/01/06 18:25:44 cache checked | panic: 0
2023/01/06 18:25:44 cache dropped | panic: 0
2023/01/06 18:25:44 cache checked | panic: 0

How to configure?

By default cdropp reads /etc/cdropp/conf.ini.

but config file location can be redefined with CDROPP_CONF_PATH environment variable

~> CDROPP_CONF_PATH=./examples/conf.ini ./cdropp -d

Default values of /etc/cdropp/conf.ini

[cdropp]

# minimal free ram trigger in mb
trigger = 256

# time between checks in ms
timer = 3000

# strength of cache drops 1,2,3
strength = 3

# debug 0,1
debug = 0

have a nice day!
