sst - simple sqlite stress test script in python.
Why? sst is a simple stress test script to test how fast is sqlite in simple create, insert, select and joins. And to compare sqlite to /dev/zero (fast writing, no reading) and to mysql. The sst sript generate his data randomly.
sst.py - main script to getopt and start the process. sqlconfig.py - the configuration file, how to create sql request and other configuration stuff, a python structur. dbs.py - the different class of database calls. getrandom.py - return different strings to populate the database . functions.py - help functions.
how to create insert: write the insert sql request: 'insert':"INSERT INTO address (street, nr, zipcode, town, state) VALUES ('%s', '%d', '%d', '%s', '%s');", then write a list which functions should be called for the insert fields: 'call':(getrandom.street, getrandom.street_nr, getrandom.zipcode, getrandom.town, getrandom.state), the call list will be iterated in for loop, append to a list and later insert%list, get joined.
Some results

Here we can see that insert is the most time consumption. And that sqlite need more time as mysql or /dev/zero.
