Dreamweaver CS3 Mac: Slow FTP

Question

FTP connect is super slow on my Intel iMac.  I have both DW8 and DW CS3, and both intermittently produce long delays while uploading files.  Sometimes files will upload in 2-3 seconds, other times I'll sit and wait for 45-60 seconds for an upload to finish.  Sometimes the upload fails entirely.  I've changed every site related setting (and tried every imaginable combination), turned off external file display and all invisible items display, but I can't get reliable upload speeds.
The crazy thing is that while DW is sitting there, I can manually fire up Terminal, type my connect to FTP server info, manually copy and paste my username and password, type my cd and lcd info, type my put with file name, and the file transfer is done before DW finishes.  Of course I don't want to be forced to use Terminal for something that's built into DW, and I don't want to switch to Finder and Fetch every time either.  If anyone has suggestions on what else I might try I'd be most grateful (especially if one of the suggestions works!).

Answer 1

I've been struggling with this problem for months, and during that time contacted Network Solutions repeatedly to try to determine the source of the problem. They won't put you in direct contact with a person who actually knows anything, but instead "escalate" issues to techs, who then send copy/paste form letters 2-3 days later saying everything's fine.
After running every diagnostic imaginable, and even reinstalling my OS, I decided to open a test account with Godaddy.com.  They got me set up in minutes, and FTP response in DW was immediate, as it should be.  Due to the fact that Network Solutions didn't lift a finger to help resolve this FTP problem that was apparently on their end the whole time, as well as numerous other problems I've been reporting for weeks, I've dropped them.  I'm very happy with Godaddy so far, and FTP has been glorious since I switched.  They even offer customer service in my native tongue, English.  Imagine that.
