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
