    \n# Redis calls an internal function to perform many background tasks, like\n# closing connections of clients in timeout, purging expired keys that are\n# never requested, and so forth.\n#\n# Not all tasks are performed with the same frequency, but Redis checks for\n# tasks to perform according to the specified \"hz\" value.\n#\n# By default \"hz\" is set to 10. Raising the value will use more CPU when\n# Redis is idle, but at the same time will make Redis more responsive when\n# there are many keys expiring at the same time, and timeouts may be\n# handled with more precision.\n#\n# The range is between 1 and 500, however a value over 100 is usually not\n# a good idea. Most users should use the default of 10 and raise this up to\n# 100 only in environments where very low latency is required.\nhz 10<\/pre>\n
