The 38400 baud might be the biggest bottleneck. http://bettermotherfuckingwebsite.com/ http://bettermotherfuckingwebsite.com/ is 20k, ignoring http overhead.

The 38400 baud might be the biggest bottleneck.

Maybe strip that to 15k after compression, and cut some content.
Still 15000/38400 <= 3 responses per second.
Add in serial parity overhead, http overhead. Might be able to sustain 2 rps with enough cleverness.
Leaves no room for bursts
- fisherjeff 5y agoDon’t forget that 38400 baud serial is 3840 bytes/s…
- arcticbull 5y ago38400 baud should be 38.4kbits/sec or 4800 bytes/sec no? [edit] never mind, you're right, assuming an 8N1 configuration - 8 bit bytes, 1 start bit, 1 stop bit, and no parity bits.
- admax88qqq 5y agoYup definitely forgot bits vs bytes lol. So 3kB/s, if your site is 15kB you're looking at 5 seconds per request, or 0.2 rps. Plus overhead. I thought my original math sounded too fast.
- Moru 5y agoA nitpick though from someone that actually used a 300 baud modem without dialing function, baud != bps [0] [0] https://www.linuxjournal.com/files/linuxjournal.com/linuxjournal/articles/010/1097/1097s2.html https://www.linuxjournal.com/files/linuxjournal.com/linuxjou...
