Performance during Data Compression

Pentium D 820 showed pretty low results in WinRAR, because this archiving utility uses only one core of the dual-core processor. So, relatively low clock frequency of only 2.8GHz prevented it from competing successfully with pentium 4 CPUs working at 3.0-3.4GHz and Athlon 64 processors boasting very efficient low latency memory subsystem.

Another archiving utility, 7zip, does support multi-threading, however, Pentium D 820 still occupied only the last place in it. The real multi-core architecture seems to be of no use here, because the apoplications is optimized for “virtual” multi-core, i.e. Hyper-Threading technology.
