I repeat 3 times the writes process and compute the mean time. I try to do a fair comparison with the classical way wich is: 1/ open file 2/ do the write 3/ close file I updated [the code](https://gist.github.com/bioinfornatics/2870d9e7dba192114f32ce8299796269) to remove time spent on SQLite database connection and Configuration as we coud consider that this operation is done only a few time during an application life ``` ./write_perf_db_txt.py database was writed in 0.5052063270122744 seconds. text was writed in 0.10451052167142431 seconds. ```
