External Email - Use Caution        

Hello Torkil,

Not sure what version of Freesurfer you are using, but if it’s an older release, it could be interesting to compare the performance with one of the latest development builds (not a release) from MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/dev/.  There’s an archive and RPM for CentOS7 and an archive for a CentOS8 build.

Hi Ruopeng

The users all agree it is GUI responsiveness. Everything else can run 
just stellar on the very same desktop, matlab etc, at the same time as 
freeview stalls.

Mvh.

Hi Torkil,

Can you tell what part of the program slows down the most? Data loading? GUI responsiveness? Image/3D rendering? Or just in general? If it is the rendering, maybe try updating the graphics card driver to the latest?

Best,
Ruopeng

Hi

We have an older Ubuntu 16.04 HPC installation on which Freeview runs
just fine. We also have a brand new CentOS 8 Stream HPC installation
with much better hardware on which Freeview slows to a crawl after a bit
of use.

There's no error as such, it just slows to the point of being unusable.

Any suggestions on how to fix it, or pinpoint the cause?

Thanks,

Torkil
