[Zope] Zope 2.6.4/2.7 Slow FTP...again.

[Thomas Bennett]

 From a previous posting from Pollard:
"It is worth noting that FTP upload is full-speed. Also noteworthy is that 
the CPU on this box is going to 100% when I download via FTP (45% user/55% 
system)."

I setup a Dell 700mhz machine with Fedora Core 1 and Zope 2.7 with Python 
2.3 and experienced a similar occurence on the client machine when trying 
to do the first upload to the server.  That is, the client machine went 
down to almost 0 ram available when connecting to the Zope ftp server with 
a Dreamweaver4 client.  I tried the old WAR FTP Client and upon connecting 
the ram went down to almost 0.  In both instances I killed the ftp client 
so I wouldn't have to reboot the client and used System Mechanic 4's ram 
defrag utility to recover lost ram on my W2k client.  I couldn't put a 
file on the server at all.  Having used DW on at least 3 different servers 
having run at least 4 different versions of Zope since the my first 
installation I found Dreamweaver _always_ needed Passive FTP turned on.  
For this new site I turned off Passive FTP on the client and connected to 
the Zope 2.7 with virtually no problem.  One or two files originally did 
not transfer well but after that files transfer fine.  I don't know if 
this might shine some new light on this but I don't recall seeing Passive 
FTP mentioned in any other threads on this topic except for excerpts from 
connections that showed going into Passive Mode on the server.

I hadn't tried a large file before so I've just tested a 4mb file with 
Dreamweaver 4 not passive ftp

put 800k/s

get 25k/s

To me this would appear to be a server side change because of the Passive 
FTP setting, but I'm not sure if it is in the OS or Zope.
