[Qgis-user] Qgis best practices

[Muki Lukuna | IT Synergy]

Good afternoon,
I work for an MSP and we manage IT for a client that recently migrated from an on-prem environment (RDS + file server in the same rack) to Azure Virtual Desktop. Since the migration, QGIS performance has degraded when opening and saving certain datasets/projects.
Environment

 *
QGIS version: 3.40.12 “Bratislava”
 *
Azure Virtual Desktop (multiple session hosts)
 *
Data stored on Azure Files / Storage Account (Premium), same region as AVD
 *
Access via Private Endpoint (no public internet path to the storage)
 *
First days after migration were OK, issues became noticeable after a few days

Symptoms

 *
Opening and saving files is slow and sometimes appears to hang
 *
For one specific dataset/project, QGIS crashes on open or on save
 *
Windows Explorer also becomes “Not responding” when opening/saving that same file set (seems I/O related)
 *
Other files can also feel slower, but the reported file is consistently problematic
 *
The file that seems to hang the most is a 2 mb file

What we are looking for

 *
Are there known QGIS settings, data formats, provider options, or project configurations that can cause heavy file locking / long blocking I/O over network storage?
 *
Any recommended best practices for running QGIS in a VDI/remote desktop setup with data stored on network file shares (Azure Files), especially regarding caching, temp directories, or avoiding certain workflows?
 *
Any logging or diagnostics you recommend (QGIS logs, GDAL/OGR debug options, crash dump locations) that would help narrow down whether this is QGIS-related vs storage/SMB/locking/latency?

Thanks in advance for any guidance.
