Hello.
Usually only benchmarks will show a real picture
for you. Create foreign keys, perform some tests. Then
temporary disable FKs using SET FOREIGN_KEY_CHECKS=0 and
repeat the performance measurement. Super Smack is a good
tool for such kind of analysis. See:
http://dev.mysql.com/doc/mysql/en/custom-benchmarks.html
