File Compression & Encryption:

Website: WinRAR

Our file compression and decompression tests were split into two halves to cover a broad spectrum of performance. The first test we ran was to compress and encrypt a 176MB MPEG-2 source file with the highest quality compression ratio. Secondly, we compressed and encrypted the folder of 400 photographs with the same compression settings.



Again, the Asus P5Q Deluxe performs faster than the other DDR2 boards and even faster than the MSI P35 DDR3 by a couple of seconds at a minimum. It's only outperformed by the Gigabyte X48 board, however that's using DDR3 and is significantly more expensive.

File Decompression & Decryption:

The two RAR archives created during the compression and encryption tests were then decompressed and decrypted.



In decompression the DDR3 boards seem to benefit slightly better than the DDR2, however of those DDR2 boards the Asus P5Q Deluxe again works best.
