performance comparison after converting from myisam to innodb

In my application I have changed the database engine from myisam to innodb.
Now I want to check the difference in performance if any.
I can run my old application if needed.

technicaly to see a difference, there must be a before and an after. In your case, you didn't benchmark your application before, then I don't see how you could see a difference... :-/

OK.  I can invoke my application with myisam in another machine. So I will have 2 machines running the application each with different engine.
idealy, with a php or a shell script I would suggest you to run a specific scenario based on realistic events on your web site, and fork it to replay almost live conditions.
Adding appropriate timestamps you could get an interesting vision of the performance evolution.

technicaly, this can be done just by your knowledge of the platform or by dumping with tcpdump the queries running live or by dumping processlist regularily. I suggest mk-query-digest to get a vision of statements spearding over a specific period.

Consider disks, memory pressure, cpu pressure and TPS to get a view of how the machine is dealing with the load on each engine.

this is always a tricky exercise to reproduce live pressure to evaluate performance evolutions.
