When I upgraded to v6.7.0, I had a performance issue which was preventing consistent data collections.  One item that *seemed* to be messing things up was the vBundle and Velocity cartridges that I had installed.  After uninstalling, things were better but still needed some additional JVM memory tweaks to make the new version reliable.  Now I find myself really wanting the dashboard objects that these cartridges brought to the table.  Is anyone running them successfully under 6.7.0?
