My applications save a good-sized hdf5 dataset. It takes a fairly long time to read back in (around 4 minutes).
If I do a simple repack on the file (h5repack infile outfile) reading it back in only takes around 1 minute. What's h5repack doing that speeds up the reads so much, and how do I implement that in my application? (I was using h5repack to test different chunking sizes, and everything I did in h5repack gave a similar time, including repacking to the same chunking scheme as the original dataset). Thanks, Peter Steinberg
