I'm in the process of writing a system that will perform various automated workflow functions, including exporting and importing of items along with updating the version and status of target jobs.   The command line utility makes these functions rather straight forward, except for it's speed, primarily during the logonProject step.  I see average durations of this function at around 5 minutes, sometimes taking as long as 10 minutes to complete this step for a single project (varying sizes, varying repository systems, etc).

Does anyone know of any tips/tricks to troubleshoot why this function takes so long, and possibly ways to speed things up.

A single round of export/import/updates for a single project through our work-flow systems is averaging 20-30 minutes.
