Today I tried to connect two laptop computers, both having Gigabit Ethernet NICs, both with Windows 7, with straight cable cat 5e. The cable is ca 50 cm long so the category 5e should be enough.
I've set static IP addresses for both and tested them through SMB, HTTP and FTP.
The response of HTTP and FTP is instant, but going to SMB share takes too long. Each folder change takes ca 2 minutes.
And finally, the real speed of FTP (Microsoft IIS to FAR manager) was ca 219 mbit/s (4053265652 bytes file has been transfered in 141 sec).
Why the connection is so slow and why it takes forever to browse through SMB share?
Update especially for mrdenny
Copying of the file over 100 Mbit/s LAN with router didn't show any significant difference between SMB and FTP download speed:
SMB: 349 seconds (88,6 Mbit/s) FTP: 345 seconds (89,6 Mbit/s)
