Don’t forget that 38400 baud serial is 3840 bytes/s…

38400 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.

Yup 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.

A nitpick though from someone that actually used a 300 baud modem without dialing function, baud != bps [0]
