Comment 19 for bug 1034999

To narrow down the source(s) of the issue I further tested. Confirming the lag is both correlated with the number of lines and exponential with the number of lines. With these latest tests the lag per action ranges from ~2 seconds with 129 lines to more than 13+ minutes lag with 940+ lines, and so on and exponential.
