You didn't say what FTP server you ran on the Macintosh.

Ah! man mount is your friend. I'll snip the relevant portion:
Mount options for fat
(Note: fat is not a separate filesystem, but a common part
of the msdos, umsdos and vfat filesystems.)
uid=value and gid=value
Set the owner and group of all files. (Default: the
uid and gid of the current process.)
umask=value
Set the umask (the bitmask of the permissions that
are not present). The default is the umask of the
current process. The value is given in octal.
So, you can setup gid=100 (or whatever your users group # is), and the
umask=770, and voila!
You now have write access!

This sounds like a Macintosh-side problem. If you're having mega-lags every
1MB, that's suspiciously like a Disk Cache size interval... maybe your drive
is mega-fragmented on the Mac-side.... You say it persists for a minute or
so? Unless your hard drive is hella-slow, and mega-fragged, it shouldn't
take that long to write 1MB.
Do a disk check, run a new Disk First Aid (the 1.6.x or newer) and repair the
volumes in question, etc, etc.
Failing that, it could be a network setup problem.
Myself, to/from my PowerMac 8500/120 with FTP [Fetch, set to 32k buffers] to
a Linux 2.0.36 machine equipped with a 3Com Vortex/Boomerang [PCI] netcard
(we have only 10BT alas), I get the ethernet theoretical limit of xfer rates
[until my Disk Cache on the Macintosh dumps - and even then, I'll sustain
nearly 1MB/sec for a 100MB file, say].
Whatever the net chip Apple used starting with the PCI Powermacs is
definitely a decent one. The ones in the Nubus PowerMacs are just OK.
