[en] Comparative analysis of the rates of statistical distribution collection by means of the HFILL and HFF1 programs being a part of the HBOOK package of service programs is made. The computer-independent and ES-oriented versions of the HFF1 program having faster one-dimensional distribution collection are described. The rates of data collection when using these versions are increased by 6 and 10 times correspondingly as compared with the HFILL program. The rate increase is achieved by intermodule realizing the functions of resulting array compression, decreasing the volume of quasidynamic characteristics calculation, taking into account the computer byte structure and optimizing the algorithms of dynamic structure element search. The results obtained give an opportunity to optimize the process of experimental data statistical processing selecting the proper programs and the mode of their operation
