https://bugs.kde.org/show_bug.cgi?id=291835 --- Comment #60 from Fabby --- Holy Moly! round(106/108*100)=98% efficiency and (nearly) 100% speed increase! Where can I send the bottle of Champagne? (or crate of Belgian beer if that's your preference...) -- You are receiving this mail because:

https://bugs.kde.org/show_bug.cgi?id=291835 --- Comment #59 from Christoph Feck --- Does "dynamic request size" mean that it starts e.g. at 256KB, then measures the time it needed, and if it was less than 1 second, then it will double the buffer size, measure again, etc. up to (say) 128MB? --

https://bugs.kde.org/show_bug.cgi?id=291835 --- Comment #53 from Krzysztof Marczak --- Maybe look for the answers in other software. Gnome-commander also uses SMB and SFTP and uses all possible hardware throughput. Maybe if you look into source code of this application,

https://bugs.kde.org/show_bug.cgi?id=291835 --- Comment #51 from Mark --- FWIW in my mind this is by no means a user space vs kernel space thing. I talked about sendfile/splice before in this very bug, back then i had no numbers to back that up. Now i do. Here's what i did.

https://bugs.kde.org/show_bug.cgi?id=291835 --- Comment #50 from Christoph Feck --- Actually, what that bug proposes is the reverse of what we need here: We would like kio-smb to use a kernel mount to speed up all KDE applications that use KIO. -- You are receiving this mail
