Subject [Bug 55612] Performance improvement (~11% up to ~92%) by adding a cache to HSSFCellStyle.getDataFormatString()
Date Sat, 19 Oct 2013 14:45:05 GMT

--- Comment #1 from Yegor Kozlov <yegor@dinom.ru> ---
Can you please explain the logic in details?

Why do you not compare lastFormat and format ? You cache lastFormat  but use it
only in a "not null" clause and not in equals. 

Why do you need to cache lastFormatSummary and collection of workbook's format
