Just to check I updated Couchbase java client to 2.2.1 to see if there was a performance improvement, then I realized this message:
DNS Reverse Lookup of 192.168.0.10 is slow, took 4512ms
so there’s 4.5 seconds I know I’m wasting, but I don’t understand why since I’m not resolving any hostname, I’m using IP (as String) as you can see on the above code. Any hints of what can I change to speed up the DNS lookup or force IP connection? That would leave the issue under ~5s and I’m sure I can disable things in the cluster environment to push that number even lower.
as always thx in advance.
EDIT Ohhh my… sorry for the duplicated question, I’ve just seen this JavaClient 2.x connection`s warning, but still I’m looking for the environment tuning part.*
