I found, that ftp transfer from Win95 to Linux got very slow.
About 1Mbyte will go OK, but then speed goes down.

Dump:
sats - Linux 2.1.103, wuftpd server.
padavere - Win95 OSR2, Win ftp client.

What appears to be happening here is the wuftpd server is not eating
the data quick enough from the socket for some reason. When it gets
this slow, you may want to strace wuftpd. I bet that you will see
that perhaps wuftpd is blocking for long periods of time writing out
the data to disk, or something like this.
