Re: FTP 400 to 400 toooo slooow

[Larry Bolhuis <lbolhui@xxxxxxx>]

Brian,

 We tested FTP across the FDDI loop this morning.  Sad to say performance was a
lowly 900KB/sec.  We sent a 20MB file across from a 310-2044 at V3R2 with no
users active to a 530-Quad at V4R2 with the CPU at 25%.  Pretty pathetic again!

 Any explenations out there?
