Reading speed of the parameters should be as before JITL-229

Current Situation

• JITL jobs needs too much time when reading job/order parameters.
  An example with 38 parameter needs:

  release	time for reading
  1.10.0	~0.4s
  1.10.2	~2s

• This performance lack is affected by JITL-229.

Desired Behavior

• Reading speed of the parameters should be as before.
