Deletion studies through RDR | Latest deletion rates for 3 GiB files: 21 Hz Desire deletion rate from ATLAS: ~ 4 Hz Latest deletion rates for 1 KiB files: 59 Hz Deletion rates measured using 10 threads (VM with 16 vCPUs). In conversation with CERN DDM, Rucio reaper is using 10 threads (for ATLAS?). Next: measure Check timings for slow deletions. Measure deletion rate for 6 GiB files. Testing with 1 KiB files works up to 4000 files (deletion client on two VMs), but fails with 10000 files. Investigating. | ||||||||||||||||||
