Hi Anindya,
If you're referring to raw data option I advise you not to use it since it goes for all columns and little aggregation will take place.
Best thing to do here is to get the SQL statement for this version, generate the planviz and do the same for the previous version (if you still have it). You will obviously need to get a working query though (filter out data in a way that allows you to do so).
There are performance-related fixes included in 102.05 so that could explain your scenario. Any chances you can set your example on an upgraded sandbox and test it out?
BRs,
Lucas de Oliveira
