I agree with Daniel's reply - I would suggest looking at your underlying
code - this is not likely to be a problem with curl, itself, but
whatever code you have wrapped your curl command in. This sounds highly
familiar with just about every other resource-absorbing Java
implementation I have worked on... It needs much, much work on
optimization to be anything close to scalable. The same command, using
curl from the command line, gives me the page, time, and exits immediately.
