thanks much for replying........ I will check on ur recommendation 1 & 2, i had not done that! I will report my findings.
I have however, checked #3. I had it on 100FD, i now changed it to 100HD, after finding that switch port was at 100HD. No much improvement, however. Currently, using net_monitor, on a local 100Mb LAN, i am getting only an average of 800KB/sec as a receiving speed!! --- Joerg Mertin <[EMAIL PROTECTED]> wrote: > On Tue, 21 Jan 2003, Tru64 User wrote: > > Hi there, > > have you checked the block sizes of all involved > Filesystems ? > Some Hints that come to my mind: > > 1.
