Enhancing Directory Operations and File Read/Write Performance

The size of pageCache directly impacts the file read/write performance. To increase the value of the pageCachesize parameter:

1. Unload NFS gateway by executing gystop.

2. Set the value of the pageCachesize parameter based on the requirement. For more details, refer to the pageCachesize parameter description in Setting NFS Gateway Parameters .

   The following parameters have an impact on the directory operations:

   • pageCacheSize: When pageCache is set to 8 MB, a directory containing 50,000 entries can be listed. Use this example to calculate the size of pageCache required to operate on your largest directory. For more details, refer to the pageCachesize parameter description in Setting NFS Gateway Parameters .

   • shadowCacheSize: Refer to the guidelines mentioned in Setting NFS Gateway Parameters to tune this parameter.

   • Btrieve CacheSize: Refer to the guidelines mentioned in Configuring NFS Gateway for the First Time .
