Package: debian-edu-config Severity: wishlist Hi all, another idea / request for bullseye...We have one school where 2 notebooks and 4 notebooks are each behind a very low bandwith line (on-site VDSL modem bridges, wired over underground telephone cable, 20MBit/s synchronous max speed).
On these network endpoints, NFS performance is really really poor. So, today I played with the FS-cache kernel implementation underneath the NFS file system.
A running stretch setup needed three things to get FS-cache working: * 'fsc' extra mount option for the autofs'ed NFS mount points in LDAP * apt-get install cachefilesd * enable cachefilesd in /etc/default/cachefilesdAfter I had these bits set up, I could observe a softer usability of the notebook I was sitting in front of. While I had to wait for several tasks irregularly during normal operation (browser, libreoffice), I could subjectively work much smoother with FS-cache up and running.
I also tested, if 'fsc' is painful to systems that don't have the cachefilesd service running. It is not. It is a no-op parameter then.
Unfortunately, the cachefilesd DEB package has fallen out of buster due to apparmor incompatibility. So, this bug report is for bullseye, I supppose. (However, we could use 'fsc' as a mount option already, so buster's edu LDAP is bootstrapped correctly for this already).
