| Requirements |
|
* For all of the following, the times measured should apply when the XO is connected to a wireless AP and running Write with a file of less than 1 MB. This is used as a sample "state of the machine" definition. Other definitions of state of the machine are welcome and the performance when the XO is doing more (e.g. more activities open or moving data over the Wireless) should not degrade precipitously.
- The time between when the user interacts (e.g. clicks or enters a key stroke) when the result is visible on the screen should be less than 100ms. Specific cases are listed below and when the absolute number above is not achievable, a target percentage improvement is listed.
- The following are examples where think release 8.2 does not meet this requirement.
- Must be 80% faster than in 8.2 to show or hide the Frame.
- Must begin showing scroll operation results in the Journal 50% faster than we do now. That is from the time I click on the scroll bar until the image on the screen starts to move.
- Must copy and paste to the clipboard and show the clipboard icon in the Frame with the right type (text or image) of object 75% faster.
- Must open a Journal detail page 50% faster.
- Must show all icons when switching from one view to another (e.g. from Home to Neighborhood etc) 75% faster.
