Scheduling and dependency issues in dots.

Hey, guys I finally got the distance check to work but my fps is really low (40 fps) for only 500 entities. I have to call JobHandle.Complete() on the job that does the check. If I don't call complete there is a dependency issue with other physics jobs.

 {
     public class NeighbourSystem : JobComponentSystem
     {
         private EntityQuery query;
         private BuildPhysicsWorld physicsSystem;
         protected override void OnCreate()
         {
             this.physicsSystem = World.GetOrCreateSystem<BuildPhysicsWorld>();
             this.query = GetEntityQuery(
                 ComponentType.ReadOnly<Translation>(),
                 new ComponentType(typeof(NeighbourElement)));
         }
 
         protected override JobHandle OnUpdate(JobHandle inputDependencies)
         {
             NeighbourJob job = new NeighbourJob
             {
                 collisionWorld = this.physicsSystem.PhysicsWorld,
                 translationGroup = GetArchetypeChunkComponentType<Translation>(),
                 neighbourGroup = GetArchetypeChunkBufferType<NeighbourElement>(),
                 colliderGroup = GetArchetypeChunkComponentType<PhysicsCollider>(),
                 rotationGroup = GetArchetypeChunkComponentType<Rotation>(),
                 entityGroup = GetArchetypeChunkEntityType()
             };
             JobHandle handle = job.Schedule(this.query, inputDependencies);
             handle.Complete();
             return handle;
         }
     }

     public struct NeighbourJob : IJobChunk
     {

             BufferAccessor<NeighbourElement> neighbourArray = chunk.GetBufferAccessor(this.neighbourGroup);
             NativeArray<PhysicsCollider> colliders = chunk.GetNativeArray(this.colliderGroup);
             NativeArray<Rotation> rotations = chunk.GetNativeArray(this.rotationGroup);
             NativeArray<Entity> entities = chunk.GetNativeArray(this.entityGroup);
 
             for (int i = 0; i < chunk.Count; i++)
             {
                 ColliderDistanceInput distanceInput = new ColliderDistanceInput
                 {
                     Collider = colliders[i].ColliderPtr,
                     Transform = new RigidTransform(rotations[i].Value, translations[i].Value),
                     MaxDistance = 0.5f
                 };
                 NativeList<DistanceHit> hits = new NativeList<DistanceHit>(Allocator.Temp);
                 //this.collisionWorld.CalculateDistance(distanceInput,ref hits);
                 neighbourArray[i].Clear();
                 for (int j = 0; j < hits.Length; j++)
                 {
                     Entity hitEntity = hits[j].Entity;
                     if(entities[i] == hitEntity)
                         continue;
                     neighbourArray[i].Add(new NeighbourElement {neighbour = hits[j].Entity});
                 }
 
                 hits.Dispose();
             }
         }
     }
 
 }

without handle.Complete() the error is:

How can I schedule the job so I don't have to complete it on the main thread?
