Follow-up Comment #15, task #6827 (project lwip):
>I'm a little concerned at the moment at the number of optional bits of code
we're adding to lwIP.
I've thought of that too :-(
>[..]nor change the array to a list. So one alternative instead is that every
time you get a match, swap the array entry with the one before it (until it's
at the start).
The redundant code could be avoided if we swap array entries. But that would
include copying 2 entries of 16-20 bytes every time. Re-linking a list would
be much faster at the downside that access to list items is slower.
2 questions:
a) is converting the array to a list really not an option?
b) should this swapping be a configuration option or always on?
To avoid swapping there and back with concurrently active connections, we
could still compare the ctimes...
