In Okular we just got bug https://bugs.kde.org/show_bug.cgi?id=327846 PDF Render time is unreasonably slow over cifs on high latency (WAN) network connections
Basically the issue is that poppler is quite read-intensive over files, reading them over and over, and since the file is "local but really remote" it takes ages to render for big files. The only solution i can think of is doing a local copy and then working on that. I saw KMountPoint::probablySlow that says /** * Checks if the filesystem that is probably slow (nfs mounts). * @return true if the filesystem is probably slow */ And then returns true if the the filesystem type of the mount is nfs, autofs or subfs. Any objection to replacing /** * Checks if the filesystem that is probably slow (nfs mounts). * @return true if the filesystem is probably slow */ to /** * Checks if the filesystem that is probably slow (network mounts). * @return true if the filesystem is probably slow */ and adding cifs to the list of mounttypes that are "probablySlow"? Or anyone has a better suggestion to fix this issue? Cheers, Albert
