Hello, You know that it is needed to read extra blocks for each 1024 blocks in indirect block mapping. People say it is inefficient. But, I think it's not that big overload because one more block for 1024 blocks is not that many number. Do you have ever seen some experimentals or documents talking about the latency of indirect block mapping? Any comments will be very helpful.
