#918 Enable midway cache refresh by default
Closed: Fixed None Opened 12 years ago by sgallagh.

SSSD has a cache update feature that can renew the cache prior to expiration to reduce the cache-miss penalty on oft-requested entries. We originally opted to leave it disabled by default (since it increases load slightly on the LDAP server).

However, I think the performance gains on the client side are well-worth the small load increase on the server side (which would still be much lower than the load without SSSD at all).

I propose that we should change the default value for {{{entry_cache_nowait_percentage}}} to be 50% (so entries would automatically refresh out-of-band when they were queried after half of their expiration time has passed).
