There is extra latency in this setup but some of it can be mitigated by using a cron job to pre-lookup / pre-cache the most common DNS names that your setup requests. Unbound can also be told to set a min-ttl on all records at the risk of answer becoming stale but I find that to rarely be an issue.
There are a handful of less expensive VM providers. Ramnode is one of them. I hear they have been improving in the last few years but I no longer have any VM's so I can't say for sure.
- giuliomagnifico 4y agoWell with unbound there’s almost no latency because it pre-downloads all the roots names. No need for cron job because it auto updates the root.hints file (usually once every 1/2 months) But I mean the latency to route all the DNS queries to my cheap VM instead of using the default ones. Thanks for the info of Ramnode!
