Slow sFTP Transfer Speed with SSH Connection (SSH2)緩慢SFTP發布傳輸速度與ssh連接（ ssh2 ）

When using FileZille, SSH Secure Shell client, CoreFTP, PSFTP and other secure FTP clients to transfer files between computers or servers, the transfer (upload and download) speed can be very slow compared with the speed achievable by FTP connection even though there is enough fast bandwidth on network and routers.當使用filezille ， SSH的安全殼客戶端， coreftp ， psftp和其他安全FTP客戶端之間傳輸文件的電腦或伺服器，轉讓（上傳和下載）速度可以非常緩慢相比，與加快實現由FTP連接，即使有足夠的快速的網絡帶寬和路由器等。

Compare with FTP which transfer speeds can easily go up to a few or tens of MB/s or GB/s, transferring files with sFTP connection typically lands you at around 30 - 60 KB/s.比較與FTP ，其中傳輸速度可以輕鬆地去到一個或少數幾MB /秒或Gb /秒，傳輸檔案與網友連線，通常地政你在約30 -6 0K B的/秒。 The main reason for the reduced transmitting speed is due to the fact that SSH, or SSH2 (which both sFTP and SCP depend on) has protocol implementation and encryption overhead that based on the amount of CPU processor and memory (used in internal flow control buffers) resources given to that transfer session.主要的原因為減少傳輸速度，是因為事實的SSH ，或ssh2 （雙方SFTP發布和SCP依賴於）議定書的執行情況和加密開銷的基礎上，數額的CPU處理器和內存（用於在內部流動的控制緩衝器）的資源給轉讓會議。 The buffers and limited availability of resources often end up become a bottleneck for network throughput of sFTP and SCP, especially on long and high bandwidth network links.該緩衝器和資源有限，往往最終成為一個瓶頸，為網絡的吞吐量SFTP發布和SCP ，尤其是對長期和高帶寬的網絡鏈接。

If you only able to transfer at a ridiculous low speed of tens of KB/s, try to download and use如果你只能夠轉移在一個荒謬的低速數以萬計的是KB / s ，嘗試下載並使用 WinSCP winscp . 。 Once installed, establish a connection session to remote machine or computer by using the following settings and options:一旦安裝後，建立連接會議遠程機器或電腦使用下列設置和選項：

File Protocol: SCP or sFTP with Allow SCP fallback ticked文件協議： SCP的或sFTP與允許SCP的後備分
SSH Encryption cipher selection policy: Move Blowfish to the first priority slot SSH的加密密碼選擇的政策：提出河豚 ，以第一優先插槽

With this setting, it’s possible to get transfer speed numerous times higher than when using sFTP over SSH2 connection.與此設置，它可能得到轉移速度多次高於使用時的網友超過ssh2連接。 However, it’s still slow if comparing with unencrypted and unprotected FTP transfer.然而，它仍然比較緩慢，如果與加密和保護的FTP傳輸。 If you don’t mind about security, FTP is the best choice.如果你不介意有關安全，的FTP是最好的選擇。
