Note that the download page lets you select from between an installer, a ZIP file, and a X64 ZIP file. To start off with, simply download ShellExView using the Download button below. Windows 10 file copy fast then slows down free#And don’t worry, it’s completely free to use. ShellExView is a super-convenient application that lets you disable unnecessary bloat from context menus fast. Needless to say, you should have all your important data on the computer backed up online or on an external drive before proceeding with editing Registry. But if you want to remove the extensions permanently and aren’t afraid to mess around with some registry keys, then resort to using the Registry Editor. ShellExView provides a distinct advantage where you can easily re-enable the graphics options should you need them later. You have two options use a third-party utility called ShellExView to identify and disable the additional context menu entries, or use the built-in Registry Editor to achieve the same effect. Hence, you can safely remove them from the context menu and get rid of the issue altogether. These items are usually present just for the sake of it and are rarely used for everyday purposes. If you see Graphics Properties and Graphics Options (Intel), NVIDIA Control Panel, or AMD Catalyst Control Center listed within the context menu, you now know why. The context menu lags when it has graphics extensions added to it after installing NVIDIA, AMD, or Intel display drivers. like this if they are too slow: # sysctl -w to say, it’s maddening when that happens, especially if you use the menu a lot. You can check this with: # sysctl -a | grep net.*rmemĪnd you can change the limits e.g. One more working example with an ssh encryption file flag (id_rsa) and a non standard ssh port 1087 instead of 22 to safe you time fiddeling with the syntax: sftp -P 1087 -i id_rsa /home/user/Videos/Īlso your sftp might be limited to 800kb/s or ~1 Mbit/s. Windows 10 file copy fast then slows down install#The same syntax applies to sftp so instead of scp text.txt it is now sftp text.txt usage examples scp interchangable with sftp)Īlso the recent version of OpenSSH should activate the daemon - at least in my case on an arch linux server but you might have to install an sftp package on other distributions. Its authors recommend the use of more modern protocols like sftp and rsync for file transfer instead The scp protocol is outdated, inflexible and not readily fixed. Since this question is not that old and no one else referred to this solution I think it is appropriate since it pushes the bandwidth to the max limit (10MiB/s in my case) unlike scp that is at arount 250kb/s so that answers your question.Īctually the same 250kb/s with rsync - at least with the port specifier rclone -Avvp cap_* -e "ssh -p 1087 -i id_rsa" a post to the openssh-unix-dev mailing list: Also ran an iperf test over TCP and noticed 2Mbits/sec with FP, and 55Mbits/sec without. Windows 10 file copy fast then slows down windows#To remove scp from the equation, I ran a Windows file copy operation across the VPN and noticed similar performance to scp with and without FP enabled. So it seems my issue is likely a NAT Traversal situation where the scp TCP data is ultimately encrypted and encapsulated in ESP & UDP packets, and consequently subject to FP. In reviewing the firewall log, flood detection was occurring on both source & dest ports 4500 over the public IP addresses, not the private site-to-site internal VPN addresses. What does SSH use UDP for? - It doesn't directly from what I read. Sender: cygwin, Receiver: Fedora 20, Firewall Sophos UTM. When turning FP back on, the rate dropped back to ~250KB/s. After disabling UDP flood protection (FP) on the destination firewall, the transfer rate increased to 6.5MB/s. Windows 10 file copy fast then slows down mp4#Just had this issue doing a site-to-site transfer of a large mp4 file via scp. The strange thing is that the transfer rate is about 413KB/s and the file size is about 413KB so really it should transfer one file per second, however it's taking about 4.3 seconds per file.Īny idea where this overhead comes from, and is there any way to make it faster? I'm trying to copy a batch of files with scp but it is very slow.
