Only the pt the wsi is bound to can service 11*1c60b9acSAndroid Build Coastguard Workerthe thread, so although there can be as many wsi being serviced simultaneously as there are 12*1c60b9acSAndroid Build Coastguard Workerservice threads, a wsi can only be service by the pt it is bound to. 13*1c60b9acSAndroid Build Coastguard Worker 14*1c60b9acSAndroid Build Coastguard WorkerThe effectiveness of the scalability depends on the load.
