Hi to all.Maybe someone can suggest me the tunning to do for my problem.
I have 2 cisco routers with a 10Mb/s-full duplex WAN connection each.If I do an FTP between from a PC on site 1 to a pc on site 2 I reach 9.8Mb/s.Great!!!!
If I transfer the same file using a simple Microsoft Copy/Paste I'm not able to do a better transfer than 4Mb/s.
What I've done:
1)Put all may LAN-switch interfaces to full-duplex 100.
2)Set all the possible MTU's to 1500.
3)Did some traffic shaping on the wan link to smoothen out the bottle neck:
shape average 10000000
service-policy output 3111-RM2-OUT
With all these things I managed to get a speed (with copy/paste) of 6Mb/s.
Does anyone have any suggestions on what else I can do or maybe missing?Is it correct that I loose that much speed if I don't use FTP? Do you think I might be albe to do better if I use some tcp adjust-mms (about 1452) on my routers?
