You don't need separate connections to transfer chunks in parallel, you need multiple Tread messages in flight at once. The only two ways to do that on plan 9 is pread() from multiple threads(procs) at once, either in an external tool like fcp(1), or in the program itself. ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/Te69bb0fce0f0ffaf-M5f334= f5b561aae6155a06c16 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
