One last question regarding utl_dbws:
I just tested the callout sto a webservice over https, comparing utl_http calls with utl_dbws calls. I found that processing times were more than twice as fast with utl_http over utl_dbws.
Has anyone else experienced this? This could be a deciding factor in what to make the standard for development in our team for callouts. Are there certain things to consider regarding the environment that may be causing utl_dbws to be so much slower?
