I used php COM to generate the excel file.
From several month ago,
The time to generate the excel file become very slow.
Before like 0-8 seconds, now it show 50-600 seconds.
But it still work, no error.
I think Windows Server 2003 or office 2007 update may cause this problem.
Not sure maybe some securety .....
I check the task manager the excel.exe run long time and take lots of cpu.
The same code working fine on win7 so far.
Anyone know why and how to fix?
