2022-11-28udp: preallocate ports sparse vec mapFlorin Coras1-2/+80
Not ideal. The sparse vector used to map ports to next nodes assumes only a few ports are ever used. When udp transport is enabled this does not hold and, to make matters worse, ports are consumed in a random order. This can lead to a lot of slow updates to internal data structures which in turn can slow udp connection allocations until all ports are eventually consumed. Consequently, reallocate sparse vector, preallocate all ports and have them point to UDP_NO_NODE_SET. We could consider switching the sparse vector to a preallocated vector but that would increase memory consumption for vpp deployments that do not rely on host stack. For reference, populating one of the v4 or v6 sparse vectors in reverse order takes about 9.8s on a skylake cpu.
