Nah, it's the same size (roughly) as the regular kernel, the main difference is it allows ISA/VLB VGA for the console driver, afaik.

      I had to build my own kernel since the default kernel simply needs too much RAM. But once USB and a couple of other niceties were removed, it ran fine with the binaries from the i386 release.

        Most of them can do more than they announce. It's like OS/2 2.11.. IBM said it can SMP across 64 CPUs but they could only test with 32 as that was the best hardware they had at the time :D

        Yesterday I found a 486 board in my collection that boots and happily deals with 256MB of EDO RAM! The speed is hare-raising :D

            The latest mTCP for DOS is available!

            This version includes some changes to improve TCP reliability on long running (but idle) connections, black & white Sixel graphics in Telnet, a Telnet emulation bug fix, and other small fixes sprinkled around.

            The source code to NetDrive (network attached storage) is also published now - enjoy reading an unholy mix of x86 assembly code talking to Golang over UDP!

              I hate this ...

              I found a really small bug in Telnet, but it's irritating. I don't want to go through the hassle of spinning an entire new update so I just patched the Zip files that I have posted at my site.

              If you downloaded mTCP recently (more than 20 minutes ago) please grab it again. Otherwise, live with my terrible bug that throws the Telnet session into Sixel graphics mode without reason. ;-0 (Pressing a key gets past it, but like I said it is annoying.)

              My apologies ...

                                I'm thinking of running it on a 120/133MHz AMD 5x86 or something like that. It should (at least) have 64MB RAM, possibly 128 if I can get it to cache the whole range.

                                A bigger challenge will be the Nintendo WII - it has, I believe, 24MB or something like that? But at least the CPU should be vastly superior to any 486..

                                  How much memory does Apache use then? It sounds like unnecessary bloat even with modules disabled. But maybe that's just me still clinging to 20+ year old impressions of Apache being bloated by definition.

                                  Do you do TLS in Apache too? On a K6-II?

                                            I'm on NetBSD and at least pkgin knows nothing about OpenBSD's httpd (I think)..
                                            Do you have any idea of the memory footprint of h2o when doing TLS and proxying?

                                              Any idea of its memory footprint in such a case? When doing TLS?

                                                Sadly not on NetBSD though :)

                                                  Damn I like the whole css-or-bust approach to styling that has. I mean I know many (most?) others do a bit of the same but this is just delightful.

                                                  So..TLS aside, what is the most lightweight reverse proxy I can use instead of nginx in front of this thing? You know, in case I would like to move the instance from this beefy PPro to, say, a or a Wii running ? :)

                                                    TIL today: secp* curves are orders of magnitude slower than X25519 and prime256v1. At least on a Pentium Pro/Pentium II-class CPU.

                                                      After a fair bit of fiddling, this instance is now .. operational, I think? And this is officially my first post here.

                                                        Posting and boosting this certainly put the box under some duress.. Changed ssl_ecdh_curve from secp521r1:secp384r1; to X25519:prime256v1; now; let's see if that helps.
