Performance in Archiving Utilities

Besides WinRAR archiving utility, which we usually use to measure the processors performance during data compression, we are going to involve a new archiving tool, which is getting more and more popular today. It is 7zip (http://www.7zip.org). Its distinguishing feature is extremely high (maybe even the highest) level of data compression today, which is achieved due to its own algorithm. Besides, it boasts an integrated benchmark, which allows evaluating the data compression and decompression speed for dictionaries of various sizes. For 7zip tests we used a 32MB dictionary.

Athlon 64 3400+ appeared the fastest during archiving due to the low latency of its memory subsystem and large L1 and L2 cache-memory. As for the fast data extraction from archives, the ALU processors performance is the major determinative here. That is why no wonder that all CPUs with Athlon architecture and 2.2GHz working frequency ran equally fast.
