Thanks everybody for help and getting me to right point.
The major point is TCPIP$FTP_WNDSIZ.
Parameter was defined on user level (DEFINE /EXEC TCPIP$FTP_WNDSIZ ).
Results:
TCPIP$FTP_WNDSIZ (kB) transfer speed kB/s
64 10021
128 19793
256 35028
512 35828
VMS is great! Just one logical on user level has to defined (no need to change system wide parameters).
Of course, Hein and Hoff are right about latency and speed of light limitation.
