1. A computing device, comprising: a processor; and a memory containing instructions which when executed by the processor cause the processor to: maintain a thread pool, comprising threads, for parallel processing of remote procedure call (RPC) requests; receive an RPC request; maintain a segmentation data structure specifying a set of asynchronous I/O events comprising a read RPC header event, a read RPC arguments event, a get RPC priority event, a call remote procedure event, and a send reply event; segment the RPC request into a read RPC header segment, a read RPC arguments segment, a get RPC priority segment, a call remote procedure segment, and a send reply segment as a set of RPC request task segments using the segmentation data structure to parse the RPC request; queue RPC request task segments, within the set of RPC request task segments, within an RPC work queue for assignment to threads within the thread pool for execution; and assign a first priority to a first RPC request task segment of the RPC request and a second priority, less than the first priority, to a second RPC request task segment of a second RPC request to cause the first RPC request task segment to be queued in a higher queue position than the second RPC request task within the RPC work queue, wherein the first priority is assigned based upon at least one RPC request task segment of the RPC request having already been executed, and wherein the second priority is assigned based upon no RPC request task segments of the second RPC request having been executed.
