Hi,
first of all we thank you for the report, feedback is always welcome especially if constructive and aimed at helping us improve so no problem indeed you did well to report the problem you encountered.
Your analysis in our opinion is correct it would seem to be a slave problem but we wanted to know: have you downloaded the latest whdload version, the one that solves the incompatibility problem reported by the user PPC damages? We would need to know if you have tried this version or the previous one and based on this we can reason and understand how to solve your specific problem.
As soon as you can please let us know so we can proceed to carry out all the tests and checks of the case, setting your specific configuration in emulation in virtual form will not be easy and in addition we do not have amigaos 3.2.3, but we will still try to reproduce the case and the slowdown you encountered on another virtual configuration as close as possible similar to yours.
Thanks again for the collaboration and see you soon
Amiga Vault Team
