This topic has been covered many times in the past, but this article will include Kingsoft Office 2009 build 1736, Microsoft Office 2007 SP2 and the new and improved OpenOffice.org 3.1.0.
Here is the hardware, operating system, software and sample files used:
Hardware:
- AMD Athlon 64 X2 Dual Core Processor 4000+
- 512MB RAM
- SATA hard drive
Operating system and software:
- Windows Server 2003 R2 Standard Edition 32-bit (all Microsoft patches as of June 2, 2009)
- Sysinternals Process Explorer v11.33
- Kingsoft Office 2009 build 1736
- Microsoft Office 2007 SP2
- OpenOffice.org 3.1.0 with Java 6 Update 13
Sample files:
- 1 page document in DOCX format
- 2 page spreadsheet in XLSX format
- 20 slide presentation in PPT format (PPT was used since Kingsoft Office does not support PPTX)
- Download these samples here (180k .zip)
Here are the results of the test:
Basically it boils down to OpenOffice.org using around double the memory as compared to Microsoft Office or Kingsoft Office, but the CPU usage has greatly decreased compared to past versions. Microsoft Excel is still ruler of the spreadsheet, but Kingsoft Writer and Kingsoft Presentation put up respectable numbers almost taking the lead on word processing and presentations.
