[GitHub] [incubator-teaclave] gaojunjie03 opened a new issue #451: 关于execution-service服务的问题

我看到这里的源码
一次只能拉取一个准备执行的任务，这里为什么不能做一次拉取多次任务比如5次，然后5次都是并发执行，然后主线程等待这5次线程执行完毕再循环下一次？
这样看execution-service一次只能执行一个task，这好像效率不是很高。是因为什么不能做并发执行呢？
(当然我知道可以同时启动多个execution-service，这样就可以并发执行多个task，但效率还是远远不够)

有一下几个原因：
- SGX EPC 大小受限，多线程不会带来太多的 performance gain
- 线程之间没有内存隔离（进程隔离），不同 task 在同一进程执行可能会带来安全隐患
一台物理机启动多个 execution-service 的方式进行并发执行应该能满足现在的需求。
