Data saving with HDF5 shows low performance
When performing acquisitions with the Dectris/Eiger2 under X-ray generator photons at ID22, the effective data saving performance is very low:
The current illumination scheme generate compressed images of ~450 kByte. Under this regime, at 2 kHz frame rate, we found a limiting saving speed on BeeGFS with HDF5-BSLZ4 of ~450 MByte/s (when 900 MByte/s is needed). The interesting news is that we found more or less the same limit saving on one NVME drive, contrary to what we expected
