Grid Engine is a full function, general purpose Distributed Resource Management (DRM) tool. The scheduler component in Grid Engine supports a wide range of different compute farm scenarios. To get the maximum performance from your compute environment it can be worthwhile to review which features are enabled and which are really needed to solve your load management problem. Disabling/Enabling  these features can have a performance benefit on the throughput of your cluster. Each feature contains in parentheses when it was introduced. If not otherwise stated, it is available in higher versions as well.

Experience has shown utilization of NFS or similar shared file systems for distributing files required by Grid Engine can have a critical share in both overall network load and file server load. Thus keeping such files locally is always beneficially for overall cluster throughput.  See Optimizing usage of NFS in Grid Engine

Starting with V6.0 load_thresholds areapplicable to consumable resources as well (see queue_conf(5)). Using this feature will have a negative impact on the scheduler performance.
  A new feature with Grid Engine V6.0 is the ability to store scheduler profiles, e. g. "qconf -ssconf >file", such as are used during Grid Engine installation. The profiles are not stored internally. With the combination of dynamically changing the scheduler configuration by loading a new profile with "qconf -Msconf <file>" and a cron job, one can switch to a leaner configuration over night and return to a user friendly configuration during the day.
