Hi Jason, A side question regarding to the performance of the GEM5. To a single threaded workload, GEM5 is normally running as the single thread in the host processor as well. Do we have any road map on the lower level library which could split the multiple sim events into different processes which could possibility accelerate the gem5 speed?

If you're using *timing* mode, then the tick number should be used by whatever object calls the read/write function and the delay is inserted there. Also, if your program doesn't have a direct dependence on the I/O device, the latency may be hidden. Enabling various debug flags should help you track this down.
