Websphere slow URLConnection

Question

We have a Websphere version 6.1 deployed on a Linux environment. To open an https connection we call openConnection() and connect() on a java.net.URL object.

Opening this connection takes aproximately 3 minutes. Once the connection is established we can write and read data very fast.

Using openssl a connectiontest (ssh console) works very fast. A simple jar application deployed on the same machine, outside of the container, works normal too, but once deployed in websphere the problem occurs.

We only have this problem in a Websphere 6.1, works fine in 6.0

Any ideas?

Answer 1

An application on the same JVM set the https.proxyHost and http.proxyPort system properties which made our connection go slow. (proxy could not find url in these 3 minutes and used a direct connection afterwards..).
