Winscp download files slow

Is important because everything that is sent has to be encrypted at one end and decrypted at the other and potentially compressed as well if that is enabled. The suggestion here is to use a less intensive encryption method they suggest that using Blowfish is usually faster than AES , try disabling compression and try moving down to SSH-1 if using SSH The VM config could be affecting, too.

It may also help if you turn off compression, if you have turned it on before. SCP is less affected by latency. In this case, it may help if you turn on compression. After googling for a while, I got a hint on a forum that I should try specifying the IP address of my server rather than the domain name, I tried that, and voila:. Sign up to join this community.

Blowfish is usually a lot faster than AES. It may also help, if you turn off compression , if you have turned it on before. Even if your connection is fast, if the server is far away or slow , it takes a time for the response to arrive back.

If the client spends this time uselessly waiting, your transfer speed will be low. When I open my settings panel it doesn't have this sub-cat??? I discovered for me, I was using a Proxy config to tunnel through a bastion host with plink. I converted that to use the built in Tunnel config and that sped up throughput immensely.

Did nothing for me. I've struggled with slow speeds from my ESXi servers for years. I just thought that there was something going on with those servers that caused the slow speeds.

I appreciate the great product that the developers put out, but it sure seems like maybe this setting should be off by default since it impacts so many different people.

Hello, I have a relatively fast freenas server connected via 10G with my PC. When transfering a big systembackup file towards the NAS I noticed that the transfer rate was only about gbit.

I did at expect something like three to four times that. No doubt that that was related to winscp ….. So there seems to be "some" room for improvement: - starting with migratio to 64 bit - and using multiple threads I understand that you are using standard librarys …… but never the less I hope that you can improve things. By the way I did turn of the buffersize optimalisation, that was a slight improvement Sincerely, Louis. And up to my surprise my PC seems to be the limmiting factor …….

Holy cow!!! Thanks for sharing this! I tried so may things to speed up this download, but it was taking forever. At hour 4 I decided to dig harder and ran across your post here. After unchecking "Optimize connection buffer size", and restarting my download I burned 4 hours when it should have taken 5 minutes.
