Data Compression

With 2GB of system memory the archiving utilities can compress data with a larger dictionary than those used today. Theoretically it can improve the efficiency of programs like that quite noticeably. However, most of the today’s popular archiving utilities do not use this opportunity. As a result there is no visible dependence of the data compression speed on the size of the system RAM.

However, the performance of data compression utilities appears more sensitive to memory subsystem latency. According to our results, a system with four DIMM modules working at 2T Command Rate falls over 7% behind the same system with two DIMM modules and 1T Command Rate.

Video Encoding

Video encoding with contemporary codecs depends just a little bit on the memory subsystem parameters. We have already pointed this out in our previous articles. Therefore, it is not at all surprising that the different size of system memory and number of memory modules installed do not really affect the performance in this type of tasks.
