[rt-users] Time taken to open ticket history

[Kenneth Marshall]

Hi Justin,

The last time I looked at this problem, the slow step is simply
preparing all of the transactions for the web. The biggest gains
were made by pruning the list of displayed transactions to the
bare minimum, by default. Then have a button to allow seeing
all of the transactions, if needed.

Regards,
Ken
