LtspBootPerformance

Registered by Oliver Grawert on 2007-04-30

In Dapper we did a big LTSP bootprocess profiling session that resulted in cutting down the bootspeed of thin clients by 30-50% and reducing the memory requirements to 64M without network swapping. Since dapper LTSP has gotten many new features, kernel and nfsroot are grown over time and low end thin client hardware starts slowing down on boot again. During UDS Sevilla a bunch of LTSP profiling sessions will take place to find the slowdown factors. Additionally the kernel config files of the ltsp 4.2 and the current ubuntu i386 image will get compared to find out if there are possible improvements through having a -ltsp kernel package or if we can make the current i386 image less memory hungry and speedier. The possibility of using nfs4 for the nfsroot and possible speedups through that will also get reviewed.
