Hi,
In SQL queries on databases like Postgresql it is common to use the Limit
operand to ask just a sample of the output to check if all looks OK without
reading the all table.
This situation made me wonder if this couldn't be a nice feature request to
the layers attribute table when working
tnx Kelly, this is your issue and it's ok:

to everyone, please add any comment or info that can help to replicate/solve

Hi,
Glad to hear that it helped to run the operations on a closed table.
Nevertheless, as Luigi said, it would make sense to submit an issue
report about this slowness.
The other thing one has to keep on mind:
The SQLite API is kind of limited. Only until recently, if you wanted to
rename
may you open an issue about this slowness with all details to reproduce?
Only with opened issue the project can allocate resources to fix them...
and we are just in bugfix period before the 3.4 release. So your
contribution would be precious.
tnx
Luigi Pirelli
Luigi, I'm pretty sure you just solved my problem. I tried a few operations
with the table closed and it was like night and day. That 400k field
calculator finished in mere moments! Thank you!!

can you test doing operations with field calculator without having the
attribute table opened? just a workaround could be to use a virtual layer
then save the entire layer later.

Hi,
I had similar problems with shp files in earlier version of QGIS. I would
reboot the Window machine and restart QGIS but the problem would start again
after a number of edits. I think it was a plugin that was causing a memory
leak. Try closing all the plugins and then re-starting Qgis.
I have a DEM for an Island with horseshoe shape, sea as no data.
When I represent it in 3D, I get all the "no data" propagated to a
much larger extension.

Hello,
I'm working with a geopackage on ~530k features, and just about everything
I try to do in the table takes way longer than expected.
- Adding a field took 5 minutes (table now has 22 total fields, so not
massive)
- Field Calculator on ~32k selected records took 8 minutes

Hi Luigi
A PDAL processing toolbox will be nice to have. This is a great addition
to the QGIS project. Keep in mind that LAStools is intergrated in the
processing toolbox but it is not free. You can make small project but
for anything serious or professiona you will need to pay for LAStools
As said by Randal, you can ask for sure to Kurt Menke

Hi Luigi,
Thanks for the response.
I’m very happy to hear that all we want to do can be done in Qgis (my boss will
be happy to hear that even more). However, that said, we are a midsize
engineering firm doing hydrology studies, roadway projects and site development
projects. We are not in
I do training - just not on this specifically. I'd have to sit and think
about it how to work this in. I'll answer in line and maybe someone has
a better answer (possibly Kurt Menke)
1. I would think GRASS would be more appropriate than QGIS. A lot of the
tools in grass are exposed in QGIS -
Hi,
All you listed is possible to process in qgis via all possibilities offered
by backend integrated in processing (GRASS; SAGA, native qgis algs etc
etc), btw about LIDAR data in a week I'll push a new provider for qgis

All,
The company I work for is in need of the following information on an upcoming
project, and my boss is asking if we need to buy ArcGIS or can QGIS do all
this; see the list below.
1. Basin delineation from LiDAR surfaces
2. Stage-Storage determination for each delineated basin
Ciao Matteo,
sarei interessato al corso e considerando che dovrei arrivare dalla
Sardegna vorrei sapere gli orari di massima di inizio corso e fine in
modo da potermi organizzare con i voli...
Grazie
