+`pihole-FTL` offers an efficient DNS cache that helps speed up your Internet experience. This DNS cache is part of the embedded `dnsmasq` server. Setting the cache size to zero disables caching. The DNS TTL value is used for determining the caching period. `pihole-FTL` clears its cache on receiving `SIGHUP`.
 
 ### Cache metrics
 
 The Settings page (System panel, FTL table) gives live information about the cache usage. It obtains its information from http://pi.hole/admin/api.php?getCacheInfo.
 
 #### DNS cache size
-Size of the DNS domain cache, defaulting to 10,000 entries. You typically specify this number directly in `/etc/dnsmasq.d/01-pihole.conf`. It is the number of entries that can be actively cached at the same time. There is no benefit in enlarging this number *except* the DNC cache evictions count is larger than zero.
