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 .
Thank u ,
Madalina
