Abstract
Techniques for performing a process during a real time collaboration by multiple users or clients on a spreadsheet file are disclosed herein which may permit calculations to be performed locally by at least one of the clients. By doing so, increases in performance are realized since only data updates need to be provided to the host machine. As such, a determination is preferably made whether calculations performed locally can result in different data. If conflicting data is a possibility, then the calculations for the spreadsheet file will usually be performed remotely by a host machine. If not, then each client capable of doing so will perform the calculations locally and then provide only the updated data to the host machine. The determination of whether to perform the calculations locally or not may also be made dynamically, such as when one or more new formulas are added to the spreadsheet file.
