--- Comment #3 from Nick Burch <apa...@gagravarr.org> --- OK, that's good. Next thing to check - is the problem with your code or file? There's two example programs that can be used to check generation speed and reading speed, try using SSPerformanceTest to check how long to generate a simple file of your desired size. Next check if your program can load it quicker or not. Now, use XLSX2CSV to read both your file and your generated test file - how slow/quick, and are they about the same speed? -- 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
