I'm running SFOS 17.5.8 MR-8 with home license and have issues with the DNS performance (server and internet performance are perfect).
My clients get the IP address of the XG as DNS resolver. In XG, the DNS is configured statit and points to 1.1.1.1 / 1.0.0.1.
I have a dozen of DNS host entries (.local) and one request route (.local2) to a DNS server behind a VPN.
After notifying slow page loading i did some debugging and it seems the DNS requests are causing the issues, i now use DNS benchmark to perform some additional testing and this confirms the issue:
Uncached performance is very bad (worst result 6 seconds for a lookup - the 2nd worst other DNS server is only 0,33s).
I run the XG for more than a year now and it seems i never had this kinds of issue, which make me think reason can be FW upgrade.
Anyone having issues ? Or could there be another cause ?
