High weight will cause higher latency for other softirq and RT processing, it's not a good idea. Even with weight/budget of 64 if there's no higher prio work to do the driver will be polled again immediately if it consumed the budget and has more packets. Do you have some actual data on how the device performs with budget of 64 and 256? And maybe perf traces to show where the difference goes?
