[2025-07-01 08:45:23] CVMFS is ok
[2025-07-01 08:45:23] Efficiency of ATLAS tasks can be improved by the following measure(s):
[2025-07-01 08:45:23] Small home clusters do not require a local http proxy but it is suggested if
[2025-07-01 08:45:23] more than 10 cores throughout the same LAN segment are regularly running ATLAS like tasks.
[2025-07-01 08:45:23] Further information can be found at the LHC@home message board.
