Without seeing the memory saving metric and error bars, these are marginal improvements. Kudos on making a thing but I'm not seeing it. I also don't have a 68k mac though so maybe I don't see this being a big deal.
> MacTCP is wonderful, but it is old, and on a 4 MB Mac Classic with a SCSI Wi-Fi/Ethernet adapter like BlueSCSI it can be slow to answer, hungry for memory, and awkward to set up.
Which... I don't own a Mac Classic, so I can't speak it its factual accuracy, but that doesn't sound like bashing.
I like to show people Hunter Cressall's parody of the Switchers ad campaign to remind/educate them that the Macs of yore were no panacea. It's hilarious and spot-on. https://www.youtube.com/watch?v=rEvYETWVK6M
