These are kernel wait processes. They are absolute normal and come with the OS, 1 per Logical CPU. As one can see you have 2 procs and I assume you have SMT activated with 2 Logical CPUs per virtual or physical CPU.

As Bakunin said, you should really not kill them. They are definetly not your problem. They are just waiting for work and help calculating your idle percentage. Leave them alone!
IBM CPU Utilization for the wait KPROC - United States

Either this box is very weak ressource wise, the application is programmed badly, or there is some other kind of performance problem. There can be problems with name resolution etc. whatever.

Start up the application and have something like vmstat -w 2 20 while it performs slow, to get a 1st impression of your system.
Also check the logs of your application, if it writes any.
