Bug ID: 489926
Summary: File transfers extremely slow when using Dolphin with
admin/elevated privileges and annoying constant
password popups
Classification: Applications
Product: dolphin
Version: unspecified
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: dolphin-bugs-n...@kde.org

Target Milestone: ---
SUMMARY
When transfering files to a device/partition that needs elevated/root
permissions, those transfers start fast but progressively slow down until they
get extremely slow, sometimes around a few KB/s, when the device in reality
supports much faster speeds.
Using a different file manager like Thunar to do the exact same file transfer
between the exact same devices or partitions, using elevated privileges, the
transfer is much faster, as fast as the devices can achieve, making it equal to
a transfer that would be done with normal user permissions.
Dolphin also keeps asking for the root password every few minutes, pausing the
transfer while it waits for the password. Makes it impossible to use dolphin
for these type of transfers, because its so slow that it can take hours, but
you need to constantly be staring into the screen to input the root password
every few minutes or the transfer stops. Dolphin should maybe "remember" the
password and not need to ask it again, at least during that file transfer, or
while it itself is open with elevated privileges.
STEPS TO REPRODUCE
1. Open dolphin as admin / elevated privileges and inside it, navigate to a
partition or device that needs elevated privileges to write into.
2. Copy a file from anywhere to that protected partition/device.
3. Notice the transfer starts fast but slows down to a crawl.
4. Every few minutes, notice dolphin constantly asks for the root password, and
pauses the transfer while waiting for the password, even though dolphin itself
was provided the password when it was first opened with elevated privileges.
OBSERVED RESULT
Extremely slow transfer speeds and password popups every few minutes, stopping
the transfer while waiting for password.
EXPECTED RESULT
Speeds at least equal to user-level privileges dolphin, and not asking the
password constantly after it was already provided.
