We compared 7-ZIP with WinRar 5.20 using the following file set: Mozilla Firefox 34.0.5 for Windows and Google Earth 6.2.2.6613 for Windows after full archiving.

Archiver	Mozilla Firefox.		Google Earth.
	65 files 85 280 391 bytes		483 files 110 700 519 bytes
	Archive size	Coefficient	Archive size	Coefficient
7-Zip 9.35 -mx	39 357 375	100%	15 964 369	100%
WinRar 5.20. -m5 -s -ma5 -md128m	41 789 543	106%	17 035 432	107%
