ClientWrite means Postgres is waiting on the *network* sending the reply back to the client, it is unrelated to I/O. So either your client isn't consuming the response fast enough, or the network between them is too slow or shaped. -- Magnus Hagander Me: https://www.hagander.net/ Work: https://www.redpill-linpro.com/
