Hi all I read some performance issues and it's said that large number of chunk can increase the B-tree which eventually decrease the performance. Also, the default cache is the smaller of 1MB or 512 chunks. My situation is that my simulation program will produce a large data, let say 1-2GB. So, I want to use HDF5 with chunk and SZIP. To achieve a good enough performance, may I ask you what is the recommend (1) chunk size, (2) cache size. The data is written to SAS harddrive. Please let me know any other issues that I should notice.
Thank you, Tuan
