# Redis configuration file example

# Note on units: when memory size is needed, it is possible to specifiy
# it in the usual form of 1k 5GB 4M and so forth:
#
# 1k => 1000 bytes
# 1kb => 1024 bytes
# 1m => 1000000 bytes
# 1mb => 1024*1024 bytes
# 1g => 1000000000 bytes

# Notes :
#   This script is a simple "helper" to configure your sysctl.conf on linux
#   There is no silver bullet. Don't expect the perfect setup, review comments
#   and adapt the parameters to your needs and application usage.
