Well, first, don't use IDE disk attachments (and /!BIOS is the default
install option, for a reason). Change that to SATA (AHCI), and use
"/f /n" on the OS2AHCI.ADD line, in CONFIG.SYS. Also, define the
disk drive as being a SSD, or VBox will insert seek delays (it
doesn't matter what the real disk is). Don't try to change it without
first preparing the guest with the proper drivers.
Whether that will speed up FTP, or not, I don't know. FTP is not
governed by disk speed, it is governed by the slowest link in the
whole chain, and that is usually something in the network. 18 MBs
is not that bad. Also, be aware, that windows changed their method
of calculating network transfer speed, about a year ago. I used to
see 20 MBs in windows, and about 16 MBs in OS/2. Now, I see
about 16 MBs in both. I have no idea what is slowing the transfer
(windows obviously got caught cheating on their performance
numbers). I can start a second transfer (from a windows machine),
using a second computer, and the same server (the old P4), and it
shows 30 MBs. Starting a third system, it will hover around 40 MBs
on the old P4, so it isn't the slower computer, it isn't the network,
and it isn't IDE, that is slowing it (the P4 doesn't support AHCI).
OS/2 to OS/2 does the same thing.
