Hi forum, Does anyone know a general reason why disabling chunk caching would improve performance? I found this to be the case in my application but can't explain why.
In a tutorial from Elena Pourmal, https://www.hdfgroup.org/HDF5/doc/Advanced/Chunking/Chunking_Tutorial_EOS13_2009.pdf : "Chunk cache size (rdcc_nbytes) should be large enough to hold all the chunks in a selection • If this is not possible, it may be best to disable chunk caching altogether (set rdcc_nbytes to 0)" Note that even though it is possible in my application, I still gain performance by disabling it. Cheers, Brock
