| In case the speed is throttled by %%CPU%%, it may help if you choose different encryption algorithm on //[[ui_login_ssh#encryption_options|SSH page]]// of Advanced Size Settings dialog (supposing you are using SSH-based [[protocols|file transfer protocol]], such as SFTP or SCP). When using %%SSH%%, file transfers in WinSCP are encrypted and encryption is %%CPU%% intensive. Either your local workstation or your server might not be able to encrypt file transfer stream at the same speed, your connection is able to transfer it. //Blowfish// is usually a lot faster than //AES//. It may also help if you turn off [[ui_login_ssh#protocol_options|compression]], if you have turned it on before. | In case the speed is throttled by %%CPU%%, it may help if you choose different encryption algorithm on //[[ui_login_ssh#encryption_options|SSH page]]// of Advanced Size Settings dialog (supposing you are using SSH-based [[protocols|file transfer protocol]], such as SFTP or SCP).

| - | In case the speed is throttled by connection latency, it may help if you use [[scp|SCP protocol]] instead of [[sftp|SFTP]]. %%SCP%% is less affected by latency. In this case, it may help if you turn on [[ui_login_ssh#protocol_options|compression]]. | + | In case the speed is throttled by connection latency, it may help if you use [[scp|SCP protocol]] instead of [[sftp|SFTP]]. %%SCP%% is less affected by latency.

| Also there's a lots to improve in performance of WinSCP itself [[bug>164]]. So it may get better in future versions. Also note that as %%SSH%% code of WinSCP is based on PuTTY, file transfers with %%SSH%%-based protocols can hardly be faster than PuTTY (PSCP/PSFTP) is. Hence there is no point asking for speed improvements, if you get the same rate with PuTTY. | Also there's a lots to improve in performance of WinSCP itself [[bug>164]].
