The cisco_temperature check makes use of the SNMP table .1.3.6.1.2.1.47.1.1.1.1.2 to gather the description of the sensors.
This table can be very large on some devices. Check_MK normally needs to fetch the whole table because of it's architecture e.g. to make the service discovery possible.
But since this table is normally static, it is not needed to fetch this large table during every check.
Check_MK is now caching this table during checking. The cache is renewed when performing service discovery (either manually or automatically via the discovery service).
