<div>Hi, Robert,</div>
<div> </div>
<div>I am very interested in the database access part, because I am also considering to add the database access code into my rule. But my current concern is the performance. </div>
<div> </div>
<div>It would be very appreciated if can let me know how many times of database access is in your whole test suite, which cost 6 seconds? Is it always validating the same user or randomly picking different users to validate -- if using the same query, database may get result cached which will result a better performance? Did you add any arbitrary object caching in your java code for performance optimization?
</div>
<div> </div>
<div>Thanks in advance,</div>
