We are using popup menus and scripts that advance to the next field based on the type of data entry that the user selects.
When adding the first few records in a portal, it takes about 2.5 seconds for the first field menu to pop up, and about 6 seconds to advance through 6 fields. This seems reasonable. But as the number of records grows, the time it takes for the first field to pop up and advance through the fields grows significantly. For instance, when there are 10 or so records, it takes about 6 seconds for the first field menu to pop up, and about 12 seconds to advance through the remaining fields.
We have tried using different strategies to advance through fields, such as using dropdown lists and tab ordering with no script triggers, this still happens. Is this a known behavior? Are there any workarounds?
