> [uBO] will increase DNS latency because it has to check each external domain again for the "true" domain. The browser API used by uBO returns the last CNAME in the chain. I consider the DNS lookup itself to be an non-issue overhead-wise in uBO because: - The browser would need to do it anyways - DNS lookup results are cached at both the browser and uBO level |
