You think Qualcomm is larger than Apple?
What could go wrong?
7 byte preamble
1 byte SFD
6 byte dst MAC
6 byte src MAC
2 byte ethertype or length
46-1500 bytes of payload (ignoring “Jumbo” frames and 802.1q tags)
4 byte CRC
12 byte IFG (which is silence, but still counts for time on the wire)
Add it up and you have 1538 bytes “on the wire”.
TCP overhead for IPv4 is 20 bytes for IP(v4) (no options) and 20 bytes for TCP (again, no options).
So 1460 bytes of data for 1538 bytes on the wire. 1460/1538 = 0.949284
So for 100M Ethernet, 94.9284Mbps is “perfect”.
For 100M Ethernet this requires 148,809 packets per second.
Edit: for 1538 octet frames, one need only process 8,127 packets per second.

She was nice. Worked at a local Taco Deli.
It’s not so much cache misses as allowing the core to run something else while the write completes.
This is why some code scales poorly and other code achieves near linear speed ups.
Ron passed away in 2012. The last thing he worked on was FreeBSD’s bsdconfig(8).
The third building (near the UT Dallas campus) was built for Convex.
Everything was in Richardson, TX, as this was a funding requirement by Sevin-Rosen-Bayless.
Steve’s son Dan is a CS prof at Rice.

You don’t want to do it very long, because they don’t make oil pressure in reverse.
The FreeBSD scheduler is at fault here. It’s that simple.

This is everywhere.
Quoting WiKipedia:
The original Sun-4 series were VMEbus-based systems similar to the earlier Sun-3 series, but employing microprocessors based on Sun's own SPARC V7 RISC architecture in place of the 68k family processors of previous Sun models.
These all proceeded the 4/60 aka SPARCstation (1), which wasn’t introduced until April 1989.
