Nextcloud extreme Slow

[gnilebein]

Steps to reproduce

1. Update to Nextcloud 16.0.1
2. Open any Page in Nextcloud

Expected behaviour

Nextcloud should run with normal performance

Actual behaviour

The call is many times slower than expected. It sesems files_external is responsible for this (See Xdebug Infos)

Could php-xdebug itself be the issue? Remove (not only disable) the entire package and try again.

[gnilebein]

No. I installed it after the problem occurred.

[kesselb]

I've seen some reports from smb users about high cpu load. Mind to try https://github.com/eduardok/libsmbclient-php?

#6865
#12505

[gnilebein]

The problem only occurs if the SMB share is unreachable.

[kesselb]

The problem only occurs if the SMB share is unreachable.

What behaviour would you expect when the smb share is unreachable? I guess we could lower (or make configurable) the timeout for smb connections ...

[gnilebein]

In the last version, a banner was displayed in the upper area if a share was not available. But it was usable.

But in version 16 nextcloud seems unusable until a certain timeout is reached. And this regardless of whether you are in the file browser, calendar or contacts.

@kesselb OMG thank you that solved my issue!!
after 3hours of debugging and desparation I finally have a fast NC instance again 🎉 🎉 :D

EDIT: I had to purge the smbclient package completely as well

[kesselb]

@gnilebein #16836 mind to try this patch?

[gnilebein]

@gnilebein #16836 mind to try this patch?

I tried. But nextcloud ist still very slow and the page load time ist very high when the mount is not available.

[kesselb]

Is the same happening with https://github.com/eduardok/libsmbclient-php?

cc @blizzz @icewind1991 smb fun ;) Do you remember any changes to the timeout logic? Is this "storage not available" message gone?

[gnilebein]

Is the same happening with https://github.com/eduardok/libsmbclient-php?

Yes it seems so. IIRC in earlier version the message "storage not available" appears. But now it seems that NC does not try to connect in background. It seems that the connection is blocking the complete process.

[blizzz]

@kesselb nope, contrary: with the php-smbclient module it should be handled now correctly, if it fais for auth issues. The best solution would be if the underyling lib would act in a consistent way, indepent of what way of talking to the SMB storage was used.

[szaimen]

I suppose this issue is still valid? If not, please close this issue!
