net: reduce allocation size in ReadFromUDP
Switch to concrete types. Bring your own object to fill in.
Allocate just enough for the IP byte slice.
The allocation is now just 4 bytes for IPv4,
which puts it in the tiny allocator, which is much faster.
name old time/op new time/op delta
WriteToReadFromUDP-8 13.7µs ± 1% 13.4µs ± 2% -2.49% (p=0.000 n=10+10)
name old alloc/op new alloc/op delta
WriteToReadFromUDP-8 32.0B ± 0% 4.0B ± 0% -87.50% (p=0.000 n=10+10)
name old allocs/op new allocs/op delta
WriteToReadFromUDP-8 1.00 ± 0% 1.00 ± 0% ~ (all equal)
Windows is temporarily stubbed out.
