I have data to process and to write into files progressively. The data
files are in the end very large, but I append to them small strings. I
suppose buffering the strings before apending to the file would be
faster. I don’t need the files to be written before the end of the whole
process (i.e. I don’t use their content).
I’ve searched for info about how File buffer its data but it seems we
can not configure anything about this, did I miss something ?
My first idea was to buffer everything myself, appending lines to a
string, or an array of strings and write when I reach a big enough
amount of data. But if File uses a buffer anyway, it would be a waste of
time I suppose ?
Do you have any advice to optimize the writing of large files ?
