Main results of testing for the efficiency, reliability and productivity characteristics of the server intended for the statistics data gathering for the Data Exchange System of SB RAS are presented in this paper. This server is intended to early detect any malicious influences and attacks from the outside networks. It also deals with a detection of an anomalous behavior of internal computers and with an identification of non-legitimate applications in order to provide a sufficient level of the network security in general. For the preliminary evaluation of the capabilities of the software/hardware complex being built, the procedure of calibration of the system was carried out. It is proved that the selected hardware platform and operating system along with the set of different collector programs support sufficient throughput. This complex is capable to process the analyzed data flow by avoiding the loss of packets and providing the trustworthiness of gathered data upon the current channel loads. At the same time the average processor load doesn't exceed a few percents. These tests run of the system have demonstrated sufficient completeness of the gathered statistical information and its adequacy to the stated goals.
