Hello Gerard, 1) The original OpenVMS PCAP did not have packet send ability, so the PCAP-VMS package was developed to provide the packet transmission capability, as well as better packet filtering features. As HP and VSI have improved PCAP for OpenVMS, they may have overwritten your PCAP-VMS libraries, or broken some linkage that PCAP-VMS depends upon. It would be much better in the future if VSI was willing to merge the PCAP-VMS functionality into the built-in PCAP libraries, so that we don't need the PCAP-VMS for Itanium (and/or Alpha, if VSI decides to support it). You might check to see which libraries are actually installed/used on your system.
2) I don't think your i2 vs. i7 performance experience is unique. I've never been able to get any of my OpenVMS IA-64 systems (rx2600 through BL860c i2) to run SIMH anywhere near as fast as Windows/Linux on i7. HP/UX running SIMH performs much better than OpenVMS. OpenVMS has different memory access and IO models than the other operating systems.

I will meet the VSI expert on OpenVMS bootcamp in Boston next week, anf I hope we will address this issue again. Any idea welcomed, of course. (It seems PCAP on VMS does'nt like larger frame with i4, because it is the only diference I can see between i2 and i4 Itanium servers, and it works on i2). 2) there is a very bad performance issue: same batch on a windows10 / i7 platform six times faster than on an i2 / OpenVMS platform. I don't think it's a normal issue of windows or x86 being better than OpenVMS / italium i2. Something goes wrong somewhere. I gave a huge working set to the host process, and it is not doing paging, I tried Decram to avoid physical I/O, asynchronous I/O is enabled for simh (and the simh configuration is the same on windows and on OpenVMS). Any help will be welcomed: ideas, tools for tracking,...
