Subject Re: Performance when resolving artifacts...
Date Wed, 08 Aug 2012 03:21:11 GMT
Sometimes one particular remote proxy is slow and can slow everything down. You can try disabling
proxies individually and see if it improves performance. If you identify one that is problematic,
you can leave it disabled or constrain which artifacts are searched there.

I wouldn't just exclude your artifacts from remote searches - with the exception of repos
like central it's better to whitelist which repos are for what (org/jboss/** for jboss, etc.).
