    01.The performance problem is a result of a couple issues on
       the host side. Prior to v2r1, the ISPF client gateway had
       issues handling concurrent tso commands due to a conflict in
       files being used to support the underlying function. Note
       that the ISPF gateway limitations were addressed in v2r1. At
       the time, RDz addressed this by artificially imposing a 1
       second minimum between subsequent tso commands. In addition
       to that, the host code that reads and writes I/O between the
       server and the ISPF gateway was not very efficient.
    

Problem conclusion

  • 01.To resolve this, the host has now been changed to more
       efficiently read/write I/O and to not impose the 1 second
       delay on commands if the host level is v2r1 or later.
