It is important to understand that uploading files will usually be slower than downloading them. The reason for this is that Internet Service Providers. People spend more time downloading than they do uploading, therefore ISPs provide more bandwidth for data to be downloaded. You can call your ISP and have this changed.


It is also important to understand that file size on the internet is viewed different than file size on your computer. Most legitimate internet files are rarely over 10MB. This includes databases, images, and flash videos. On average, most web files are much smaller than this. If you are trying to move files at this size or larger than this, it may take awhile.

The following are reasons an FTP client times out or the transfer is slow:

1)Firewall- Test for a Firewall here. The firewall scanning process may slow the transfer of data. Close your FTP program, disable the firewall and try again.

2)Anti-Virus Program- The antivirus scanning process may slow the transfer of data. Close your FTP program, disable the antivirus program and try again.

3)If you are experiencing connection timeouts- Many FTP clients will have to start over from the beginning if they lose connection. I highly suggest that if you have one of these, either upload smaller batches of files at a time or get an FTP that will start where it left off once the connection is re-established. I highly recommend FileZilla. It is completely FREE and it will work on Mac, Linux, or Windows PC.

4)Your provider may have too much traffic already on their server. Shared hosting providers, specific budget hosting providers often have heavy traffic loads on their servers because 500-1000 customers will share a single server. If you are having timeout issues during the same time of day each time, this may be the problem.

5) Every once in awhile, you will come across an FTP system that can not handle special characters. The system will often times authenticate and establish an initial connection but immediately terminate the connection after authenticating. Usually it is older FTP clients, such as the old Fetch FTP that you may experience this with. If your user name or password has a special symbol, I would suggest attempting to try another FTP client. I highly recommend FileZilla. It is completely FREE and it will work on Mac, Linux, or Windows PC.

6) The last reason you would have a problem with timing out is if there are DNS or routing issues. The internet is a big place and a disconnect can happen at any point from you to where ever the servers are located. I would suggest trying a ping to see if there is any data being lost. You can also check some major points on the internet itself to see if there is an Internet Service Provider issue happening.
