Bug ID: 66532 Summary: [PATCH] Improve performance of SheetDataWriter Product: POI Version: unspecified Hardware: All OS: All Status: NEW Severity: enhancement Priority: P2 Component: XSSF Assignee: dev@poi.apache.org Reporter: matthias.raschho...@gmail.com Target Milestone: --- Created attachment 38524 --> https://bz.apache.org/bugzilla/attachment.cgi?id=38524&action=edit Patchset of SheetDataWriter Performance tests showed that creating rows in a SXSSF sheet with lots of data spend a substantial amount of cpu time escaping the strings to write using #outputEscapedString. By simplifying the loop and avoiding to convert between string and codepoints a bunch of times, we can improve the writing speed by a good amount. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@poi.apache.org For additional commands, e-mail: dev-h...@poi.apache.org
