xforms:repeat Performance Bug

I have been using the Xforms:repeat to build a sortable table in 3.0! I am using OPS 3.0.beta3.200510091802.

At the moment the titles of the table are xforms:triggers, which when click set values in an instance and send this off to sort.xpl

Once its sorted the data comes back and is displayed through a repeat. I notice that the XPL takes only 5 seconds (if that) to run, the application freezes for up to a minute, or longer if there is are a lot or repeats. When the application comes back to life I find hundreds of dispatching events all the xforms-element-60 which is one of the repeat outputs. In my example I have 34 repeat rows, it cycles for the events of each row at least 5 times, before proceeding to do the same on the next row, until its done. This is a major performance issue and the page itself only takes 3 seconds to load the data from tamino and do the original sort, but then takes more than a minute to sort it again?!?!?!

Any ideas

I would say that if the browser takes 60 seconds to display, there is a
problem with OPS, or the browser, or both ;-) I assume you are using
logging to see the events. Does logging itself take a lot of time, i.e.
if you disable that, is performance ok? Or is the time mostly spent then
in the browser?

Any way we could reproduce this?
