Hi, all!
Very interesting result was given by profiling w3af start (main() call) by
standart profile module:

as you can see on cold start we execute about 62 SQL queries!
It is because in many plugins we use disk_list as storage:
$grep -R 'disk_list(' * | grep -v 'svn' | wc -l
68
What is workaround for this problem?
May be we will load plugins body only after enabling of pluing in UI?
So cold start will load only core and plugins informaion like name, info and
params?
