In one embodiment, a method includes using an owner gateway node to write data for a fileset, determining whether to utilize other gateway nodes to handle a portion of write traffic for the fileset, selecting a set of eligible gateway nodes based on: a current internal workload, a network workload, and recent performance history data in regard to workload distribution across the other gateway nodes, assigning and defining a size for one or more write task items for each gateway node in the set based on a current dynamic profile of each gateway node, providing availability to in-memory and/or I/O resources at each gateway node in the set to handle assigned write task items, and distributing workload to the set of eligible gateway nodes according to the size for each of the assigned write task items for each individual gateway node in the set of eligible gateway nodes.
