Warum sind meine FTP-Downloadgeschwindigkeiten langsam?

FTP is one of the most common methods used for transferring files from a remote server to your computer. FTP transfer can have an ideal experience if FTP speeds are maximized but that is not always the case.In dieser Anleitung, we will provide all the information needed so that können Sie troubleshoot your problems and finden optimal Lösungs, and use most of your resources for better speed performance.

2. Possible Speed limitationsYour network Bandbreite is the most imPortant factor which determines your FTP speed. Knowing your network Bandbreite would enable you to understand the network resources verfügbar at your end.
• FTP Speeds metrics:Your ISP may have provided your Bandbreite in terms of MB/s or Mib/s which have different meanings. So let’s first get our speeds metrics understanding right. We will use 1 Mbps (Megabits per second) as the base unit.

• One Mbps = 1000 Kbps (Kilobits per second). 
• 1 Mbps = 125 KB/s (Kilobytes per second).
• One Mbps = 976.5 KiB/s (Kibibites per second). 
• 1 Mbps = 122.07 KiB / s (Kibibytes per second). 
• One Mbps = 0.953674 Mib/s (Mebibites per second).
• 1 Mbps = 0.125 MB/s (Megabytes per second).

• Network Bandbreite Limitations:
  Most ISPs advertise their Internet Herunterladengeschwindigkeits in Mbps. While it is technically correct, it confuses many consumers, because their testing tools display other metrics. Some ISPs also advertise only their asymmetrical speeds. They show how incredible their Herunterladengeschwindigkeits are but don’t mention the Hochladengeschwindigkeits, which sometimes are 3x slower. To know your real Bandbreite, measure it using online testing tools. Sie können use tools like ookla speed test which provides you all the details from your Hochladengeschwindigkeit to Herunterladengeschwindigkeit and also the correct speed metric used for measuring your speed.

• Network Hardware Limitations:
  Your Local machine’s limitations – A computer with low CPU and ram memory can result in slower FTP speeds but a high-end computer with average network Bandbreite also doesn’t give encouraging speeds.
  Wi-Fi connections are slower due to packet loss and delay. Wi-Fi protocols like 802.11n supPort high-speed Bandbreite up to 300 Mbps but they are not ideal choice for constant hochladening and herunterladening.
• Testing your FTP Herunterladengeschwindigkeits:
  Sie können test your FTP Herunterladengeschwindigkeits using popular free-to-use tools like Tele2Speedtest. This service allows you to test both the hochladen and Herunterladengeschwindigkeit through your FTP client without providing a Benutzername and Passwort.

2. FTP working mechanism and protocols:
2. How FTP works?FTP works as a basic server/client protocol. In simple words, a network connection enables you to send and receive files with each other. It uses the TCP/IP protocol model for communication and for file transfer. It uses Port number 21 for creating connections but the downside of FTP is that it doesn’t provide encryption.The FTP Client provides: 

• Seedbox Anmeldung Anmeldedaten.
• FTP commands. 
• browse directory

The FTP Server provides

• Authentication.
• Directory display
• Port assignment.

Let’s understand the functionality of FTP keeping seedbox in mind:

2. Ihre Seedbox provides Anmeldedaten and IP or Hostname to access Ihrer Seedbox (FTP server) remotely from your computer (FTP client)
4. You anmelden remotely into Ihrer Seedbox from your computer.
6. From Ihrer Seedbox können Sie herunterladen files as the FTP server in Ihrer Seedbox provides authentication and assign Port numbers (21,22).
8.  Sie können now use your FTP client as an interface to connect to your FTP server as it takes login Anmeldedaten, sends FTP commands, and browses through the file directory.

2. Alternatives to FTP:Apart from FTP, there are many other protocols and applications which provide much better security and file Übertragungsgeschwindigkeits compared to FTP. A protocol like SFTP(SSH File Transfer Protocol) works through SSH and provides much better security over FTP. HTTP and HTTPS provide much faster speeds along with good security features which makes it a good alternative to FTP as a whole.
4. FTP vs SFTPThe main difference between the two protocols (FTPS and SFTP) is their way of functioning. There is a performance overhead on FTPS since it needs multiple Ports. For every new transfer file is requested, FTPS requires a new Port for the data channel. The upside of this is that the control and data channels run asynchronously in two different connections; this exclusive data channel makes transfers much faster. While the  SFTP needs one Port number for all communication to the data channels, making it much easier to secure and with less performance overhead. But having the same channel for control and data can turn out to be a bit slower.
6. Configuring your FTP client for maximum speed
2. Concurrent Herunterladens:The concurrent herunterladen is a technical concept where it gives the ability to herunterladen multiple files simultaneously at the same time using FTP. FTP applications that supPort this feature create multiple connections to the server for herunterladening. It is very beneficial when someone is trying to herunterladen a folder of files. Let’s assume that  there is a session Bandbreite limitation then creating multiple connections will eventually exceed the provided per session speed which will result in an overall improvement in Herunterladengeschwindigkeit.Free to use FTP clients which provide concurrent herunterladens are – FileZilla
4. Segmented Herunterladens:A fragmented herunterladen is actually a file transfer concept where a large file at the sender end is broken into fragments or pieces and these pieces are sent to the receiver through multiple FTP connections and at the receiver’s end these pieces are recombined to produce the original file.In this FTP transfer technique fragments of a single file are herunterladened simultaneously through multiple FTP connections and nach herunterladening these fragments these are recombined to create the original file.Free to use FTP apps that provide this capability are: BitKinex, CuteFTP Pro, Progressive Herunterladener (MAC)
6. Other settings which can improve FTP speedsFTP Speed limits: Please make sure that your FTP client does not have any herunterladen/Hochladengeschwindigkeit limits. FTP active and passive mode: Wenn Sier FTP is hosted with NAT( proxy or VPN), the FTP Passive mode should be configured. The passive mode seems to be slower than active.
8. Let’s verify the network Loss of packets within the network can also contribute to slower FTP  speeds.
