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.

thank grey...will look into it

hi grey...found it grey..is there any reason job id did not generate any log?

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
