A ftp for a the file 300MB on the same network was done twice as fast (15 seconds instead of 30 as in TSM case ) thanks for the suggestions on checking the network . Are any parameters in dsmserv.opt that have to be changed ? I was allways installing with the default. And in OS ... i don't know what is expected to be on AIX regarding VWtunning or network parameters .
