I have just upgraded from 4.0.7 to 4.2.0 & 4.2.1 beta 1 and have noticed a performance issue in both 4.2.0 and 4.2.1 when using locked columns and cell editor on a remote store.

The more rows I have in the grid the slower it becomes to respond. In a grid with 100 rows and 25 columns simply checking/unchecking a checkcolumn cell takes 3 seconds the same applies when completing cell edits in other fields. If I increase it to 200 rows performance degrades further. It is only really usable with 25 rows or less.

When I remove the locked column feature there is no performance issue and in 4.0.7 there was no performance issue with the same setup of locked columns.

Has anyone else experienced this? and are there any workarounds?

I haven't heard of that issue to my recollection. Any idea if the performance issue is observable with a local store? What browser / browsers and OS? Any way you could provide a sample test case to demonstrate the issue you're seeing?
