blk*.dat files have a maximum size of 128 MiB, and new files are simply started if the block that is about to be written to disk would cause the file to exceed this size limit.
The PR that introduced this limit, https://github.com/bitcoin/bitcoin/pull/1677, suggests that this limit was chosen to reduce disk fragmentation of the files. However, I don't think there is anything that determines or indicates that this size is "most efficient", whatever that means. This is often the case with many of the maximums that exist throughout Bitcoin and other protocols - maximums are often "it just feels like that's a big enough number".

It seems that the limit was set to prevent excessive fragmentation, since the blocks range from 1 to 4 megabytes and we don't want to handle large numbers of files. I apologize, when I talk about efficiency I'm referring to how this size can provide better read/write performance within the node. For example, in the Google File System paper, a chunk size of 64 MB was determined by user behavior because a larger chunk size significantly reduces the amount of interaction required between clients and the master node for read/ write operations.
Hello,
I notice that the Bitcoin database is stored sequentially in blk*.dat files, with an average size between 128 to 134MB. I would like to know how this average size is determined and if there are any tests that demonstrate this size is the most efficient.
Regards.

Currently I have the idea of a European investor, who wants to send Bitman equipment to Latin America, Watt is more economical here.
I can afford the electricity and internet consumption.

alguna moneda sugerida por tu experiencia? Compro un Antminer S5 y estoy escogiendo el mejor pool, actualmente estoy entre el antpool y el BTC.
el BTC dice que produce 0.5Dolares al dia por un tera, no tengo los datos exactos de antpool
quiero saber sus experiencias con los POOL y que me recomienda.
Tambien quiero saber algo sobre PPS PPLNS PPS+ he leido que son tipos de porcentaje que cobra el pool ¿cual es el mejor?
