Hello All , I've just been doing a few tests on some 2514 routers I had laying around . I setup the two ether interfaces & on each like the diagram below +--------+ +--------+ | 2514 |+----------------------+| 2514 | +--------+ +--------+ + + [hub] [hub] + + +---------+[ ftp source ] +---------+[ ftp source ] I noticed a drastic lessening of expected bandwidth thru the routers . On the range of seeing only 24-25% of available ether bandwidth . But when I plug the two 'ftp source's into the same hub I am getting a more resonable 66-75% of the available ether bandwidth . Has anyone any info on what might be the cause of the lack of expected thru put . Tia , JimL +----------------------------------------------------------------+ | James W.
