Answer : check domino performance

I am so sorry I forgot to mention the performance case :

1- Check the  DDM the good feature issued with Lotus Notes7

2- you can also check the Log files
3- Check the console of each server and if you get any error .
4- Finally, if you are using windows server platform you can ,,,, "Start" ===> Run===type "Perfmon"

Then check the CPU , Memory and the Network utilization .
