[security-dev] managing OTP

[Pedro Igor Silva]

Hi Bolek,

   Do you have any reference from where I can get the PL-IDM 1.x performance metrics and numbers ?

   Wondering if we can use them as a goal when running 2.5 tests.

Thanks.
Pedro Igor

Please don't think thousands. It will show nothing :) It is a good exercise to make to feed your storage with 1M users, 200k of groups and/or roles, define membership and etc. Set at least 20 attributes for each user. Perform some operations - like mentioned setting credentials. Make sure to perform various types of queries. This is the level at which your SSD, 8GB of RAM and quad core CPU can't fake you anymore. 

Relatively quick and simple to setup on your laptop but quite good to identify weak spots in storage implementation. This is also fairly true scenario. Enterprise class customer can easily have that number of external users. Bigger organisation will have crazy amount of groups in LDAP and you may need to sync all of them into DB. Also with so flexible schema developers will abuse it by mapping all possible permission types to big set of roles - even if you could do it more efficient in different way. Sadly you cannot ban wrong usage of your model ;)

As you are currently discussing JDBC storage I would suggest implementing such tests early. Outcome can easily lead you to complete redesign of your storage implementation. Also it matters to measure time of certain operations and see how they scale depending on numbers of users. This can also help to identify leaks like the one pointed by Bill. Also my personal assumption is that with so flexible implementation like you have with JPA you won't be able to maintain scalability easily. It is better to verify. It took me and Marek a lot of time and careful fine tuning to make it perform for JPP and it didn't happen without tradeoffs. 

This is the PL IDM 1.x experience to share :)
