There are other benefits of the Arca Noae Drivers & Software subscription for virtualized users of OS/2, including full shut down and virtual power off of the VM when using Arca Noae’s ACPI PSD. ![]() In addition, while the above tests were run using the Intel PRO/1000 MT Desktop (82540EM) virtual network card in the guest, the MMLEM driver also supports the Intel PRO/1000 T Server (82543GC) and Intel PRO/1000 MT Server (82545EM) virtual network card options available in VirtualBox 5.x, either of which may yield even better throughput (the older IBM-supplied driver does not support these server-class cards). If you are transferring large files across your network to and from your OS/2 VM, this implies a possible reduction in the amount of time it takes for such transfers by more than one half 2. A 32-bit Linux guest does not show this falloff.)Īs you can see, peak transmit throughput, using 16k byte packets, went from 24.83MByte/s (198.64Mbps) to 50.39MByte/s (403.12Mbps). (Note that the falloff between 16 and 32k appears to be an issue within VirtualBox itself, as the same tests, when run against the host machine, actually report an improvement in throughput for the 32k packet size over the 16k one. Packet size 32k bytes: 28.07 MByte/s Tx, 19.19 MByte/s Rx. Packet size 16k bytes: 50.39 MByte/s Tx, 22.74 MByte/s Rx. Packet size 8k bytes: 39.91 MByte/s Tx, 19.29 MByte/s Rx. Packet size 4k bytes: 27.93 MByte/s Tx, 14.98 MByte/s Rx. Packet size 2k bytes: 18.65 MByte/s Tx, 12.20 MByte/s Rx. Packet size 1k bytes: 13.19 MByte/s Tx, 9183.80 KByte/s Rx. Packet size 32k bytes: 19.52 MByte/s Tx, 17.82 MByte/s Rx. Packet size 16k bytes: 24.83 MByte/s Tx, 20.62 MByte/s Rx. Packet size 8k bytes: 23.72 MByte/s Tx, 17.62 MByte/s Rx. Packet size 4k bytes: 22.38 MByte/s Tx, 13.58 MByte/s Rx. Packet size 2k bytes: 19.64 MByte/s Tx, 11.99 MByte/s Rx. Packet size 1k bytes: 15.04 MByte/s Tx, 9168.71 KByte/s Rx. Some comparisons from netio 1.3 across a 1Gbps unmanaged switch, from an OS/2 VM running the latest 32-bit TCP/IP stack to a 64-bit Linux server running on bare metal 1: This driver is a breakthrough for virtual machines running under VirtualBox, with performance measured at more than twice the throughput of the older driver. Arca Noae subscribers may use the all-new MultiMac Legacy EM driver (MMLEM). The result? Performance just slightly better than the default AMD PCnet-FAST III virtual adapter. Until now, the only choice for OS/2 was the older, IBM-supplied, Intel E1000 driver. Convenience of shutdown/poweroff in a virtual machineĬurrent VirtualBox recommendations are to use the virtual Intel network cards for guest machines and to configure for bridged networking. This entry was posted in Arca Noae, Tips on by Lewis Rosenthal. Follow the same procedure as when you initially ordered (or as outlined here) to retrieve the download within a few minutes. Visit the link referenced above, and instead of a download, you should receive a notice that your ISO is being prepared. ![]() Tip: ISO downloads are only kept available for a limited time, after which they must be rebuilt. Looking at the order details, you should see the following text beneath the product:Ĭlick the link and you should be greeted by a file to download. In the list of orders, the top one should be the most recent. On the left, click on the Orders and Subscriptions link, which should be the second item from the top, just beneath Dashboard. Log into your ACCOUNT page from the main site menu. So, in case you have ordered and it has taken more than ten or fifteen minutes for the email to arrive, here’s what to do: Adding the download link to the second email notification was a convenience feature. In fact, the second email notification (the one advising that the ISO is ready for download) was supposed to only include a brief note that the ISO was ready for download and that the customer should log into his or her account page here and access the order to reach the download link. Emails…well, let’s face it, you should never underestimate the power of an email not to arrive when you need it the most. ![]()
