Hi All, Thanks for all the reply.In this month,we have tried lots of way to resolve the issue and unfortunately the issue is still the same. The report perform very slow on IE/Firefox/Chrome, IE would get the memory leak message and others would crash then sas service would be unavailable. I know the size of dataset and the report design would affect the performance. In this case,there are 20 tabs and 5 dataset is used in the report. The biggest dataset on CAS is 7GB. After many testing,We found that the size of dataset is the key point.Other report with smaller data size(less than 1GB) would perform smoothly(but still slower than VA). Now we are trying to increase the number of cas cache disk,hoping that increase the I/O would help.We will get back to the community once we get the new update. Any suggestion and ideas would give us the big help! Many Thanks, Roy
