That's far too much. Just 1 example out of many: Sa 16 Mai 2020 08:16:29 CEST \| LHC@home \| Started download of 0jKMDmJGytwn9Rq4apoT9bVoABFKDmABFKDmhr8SDmABFKDmcDAHmm_EVNT.19651959._000500.pool.root.1 Sa 16 Mai 2020 09:15:21 CEST \| LHC@home \| Finished download of 0jKMDmJGytwn9Rq4apoT9bVoABFKDmABFKDmhr8SDmABFKDmcDAHmm_EVNT.19651959._000500.pool.root.1 ID: 42509 · Reply Quote

Look at the timecodes from one of my Atlas native tasks: [2020-05-17 12:01:36] Probing /cvmfs/atlas.cern.ch... OK [2020-05-17 12:14:17] Probing /cvmfs/atlas-condb.cern.ch... OK Nearly 14 minutes no response... I also notice that current tasks seems to be interrupted while working and therefore take longer overall.

I don't know if that is related or not. I expect not; it is just the same old stuff. (I have only native ATLAS and CMS selected, and no other BOINC projects). EDIT: I just downloaded 9 more native ATLAS, to fill me up. They came in fast. I have a good connection to CERN, when they make use of it. ID: 42525 · Reply Quote

OK [2020-05-17 12:43:15] Probing /cvmfs/atlas-condb.cern.ch... OK [2020-05-17 12:58:05] Probing /cvmfs/grid.cern.ch... OK 15 minutes for a response. Console command 'cvmfs_config probe' has the same problem. I just restartet my whole network and internet infrastructure, just in case it's ISP related. BTW: I don't have any trouble downloading new tasks either, they come as fast as usual.

This is a result of a task running on a machine that worked flawlessly for over 9 months now: https://lhcathome.cern.ch/lhcathome/result.php?resultid=273695262 On that same machine the cpu efficiency went down from 0.96 to 0.6.
