--- Comment #1 from Per Lewau <[email protected]> 2010-12-01 08:04:01 EST --- Created an attachment (id=26362) --> (https://issues.apache.org/bugzilla/attachment.cgi?id=26362) A patch to speed up serialization I have also had this very problem with the Poi trunk. I used Alexander's approach and that produces a great speedup. It is still worse than O(N) but it's a lot better than the original version (3.5 to .8 seconds). Serializing Excel ought to be O(N) where N is the total number of rows, but I'll admit I know nothing about the Excel file format. I have attached a patch against Poi 3.7 that implements Alexander's approach. In addition to his version I discard the values list when the map is modified. -- Configure bugmail: https://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
