Hi All

Hi Faiez

I would recommend to follow this link below and use our Performance Analysis tool. It would give you a breakdown of where we see a bottleneck and also provides tips and examples on how best to improve the speeds.

If you open up aux copy job history from the admin list. right click your job [592185] and send logs 

Have it save locally on your Commserve and then you should see the logs for cvperfloganalyze
