Web anonymization tools have been used for a long time, primarily by the users afraid of possible undesirable consequences of their on-line activity on the web. The paper analyzes both historically proven anonymization tools like TOR and newer tools, namely JAP/JonDo and CyberGhost VPN that are based on slightly modified technological principles. The primary focus is given to the measurement and evaluation of the latency increase and the transmission speed decrease in comparison to normal (non--anonymized) web browser operation. Results show that all anonymization tools being subject of the analysis provide relatively moderate latency increase. On the opposite, the transmission speed decrease was more significant, especially for JonDo.This confirms the conclusions of previous studies resulting that no anonymization tool is suitable for daily web browsing. On the other hand, in the case when higher anonymity is required, their use can be reasonably comfortable from the point of view of latency increase. However, their usefulness for downloading larger files is always disputable.
