Have you tried the "fast" flag for the $_ports option? And does it load your CPU to 100% ?
So, with great joy I tried 1.1.5 since one of the points listed was that I/O was improved,
But this was only for the I/O that is done via some filesystem device nodes and for the socket I/O. So networking performance is really improved, but the port I/O is unaffected. Furthermore, unless you use the "fast" port I/O, it can be even slower now due to a client-server approach.
Are there any alterations I need to make to the dosemu.conf file between versions, or can anyone think of anything else I can try either with 1.1.5 or a previous iteration?
Maybe it is due to some changes in configuration, but this can be a bug just as well. Does your driver uses some particular IRQ that you specify in $_irqpassing ? Try producing a debug log, such as -D9+T for ports I/O and -D9+r for IRQs and maybe this will shed some light on the problem. And then also you can see in what 1.1.4.x pre-release the problem started to happen.
