Hi! I have 2 iSeries(os 6.1) in different data centers . Speed of file transfer is about 200 mbit per sec. through 1000Gb adapter when I send 1 file by 1 batch job (SBMJOB CMD(SAVRSTOBJ OBJ(SAVFILE) LIB(SAVLIB) RMTLOCNAME(SYSTEM1)) ). The transfer speed grows to 800 mbit per sec. when I send 5 files in the same time by 5 batch jobs through 1000Gb adapter. Why speed so little in the firs case? May be SNA has any limitations speed for transfer 1 file?
