We identified a significant performance issue when using the Configuration Worksheet in NAV 2013 R2 (Table 8622, Page 8632)
Opening the page takes an unexpected long time until records are displayed, also scrolling through records and create new records is slow compared to NAV 2013 where operating this page doesn't show any performance problems.
I was able to identify some flow fields on table 8622 which reference to table 2000000028 Table Information as the source of the issue, such as field #8 "No. of Records".
Removing these fields from the config worksheet page improve performance back to a normal state.
Assuming the SumIndex calculation on the virtual table 2000000028 causing the issue, does anyone made similar experiences so far and/or has a solution for this issue ?
