However, since this value is dependent on memory and samba server settings, that means it has to have a bit of logic in it to determine the correct value (just a define won't do). Thus the MAX_XFER_BUF_SIZE in KIO should be set to 65535 if i'm reading the documentation correctly. Samba defaults to large readwrite to true and server signing to disabled as can be read here: They also default to disable server signing.

On windows they default to enable CAP_LARGE_READX and CAP_LARGE_WRITEX. But this is only true if the SMB signing is not turned on (we will discuss this further in the next section). Quote: 'If CAP_LARGE_READX or CAP_LARGE_WRITEX capability is enabled on the SMB Negotiate Server Response, the maximum buffer size used is 61440 (60K) for large read( SMB_COM_ READ_ANDX ) and 65535 (64K) for large write (SMB_COM_WRITE_ANDX), regardless of MaxBufferSize. > cifs has done it since that gives the best performance for me.

There alse were beta and rc releases where it could also have been tested. This bug was reported more than a year and a half ago, a patch was provided, and successful test reports have been provided. I agree that it should be thoroughly tested, but here you can see that it has been tested by some people, and I guess that also by other people that didn't comment on this thread. Changing a buffer size is not a complete rewrite or any mayor change. Introducing regression is obviously not something i'd > thoroughly tested to see if that buffer size can be expected to work like a > Frederico, we can't 'just' increase the size in the smb slave. I doubt 'smb' has any maintainers right now so I will reassign this ticket to the fish ioslave for you. Hence this ticket needs to be opened against both the 'smb' and 'fish' ioslaves in order for whom ever maintains those ioslaves to add support for this optimization. usr/share/kde4/services/videodvd.protocol:copyFromFile=trueĪs you can see only sftp and ftp implement the afforementioned functionality. usr/share/kde4/services/videodvd.protocol:copyToFile=false usr/share/kde4/services/trash.protocol:copyToFile=true

protocol files, you will see which ioslaves implement the optimization and hence provide a much more comparable download speed: That is because neither kio_smb nor kio_fish implement the optimization that allows ioslaves to directly save the content they retrieve from the network themselves instead of sending it through IPC to the client. Transfer speeds ranging from 70 MB/s to 100 MB/s on a gigabit network. Transfer speeds ranging from 18 MB/s to 21 MB/s on a gigabit network.

Wait for a long time for the files to copy. Copy any file to your local system from the remote system (best seen with large files).ģ. Connect to a remote file server using your chosen protocol (fish, smb, ftp).Ģ. I used to be able to use sftp instead of fish, but that is missing from Sabayon (or KDE 4.7.4, not sure).ġ. This has been happening with every version of KDE from version 4.3, no matter the release. On the command line, using scp, I get 87 MB/s. On Sabayon, OpenSUSE, Fedora, Kubuntu, or compile my own with Gentoo, all network copying done through KIO doesn't get higher then 22 MB/s.

This is true whether using FileZilla for sftp or ftp, or Explorer for the samba connection.

When copying a file from my server (Ubuntu 11.04 server, samba 3.5.8), my Windows install copies at around 90MB/s.
