Did you guys follow up on that ?

Kieran,

I agree that changing the defaults to be more generally applicable is
probably a good idea(even most small embedded systems are seeing more
RAM/ROM available these days).

Perhaps rather than a separate file, maybe it would be less invasive and
clearer to new users if we were to add a TINY_FOOTPRINT switch to the
existing file that would define the current minimum (conservative)
setting defaults?

i.e.
----------------------------
#undef TINY_FOOTPRINT  // DEFINE for very resource-limited targets

#ifdef TINY_FOOTPRINT
.
(old values here)
.
#else
.
(more reasonable default values here)
.
#endif
----------------------------

Just my initial thoughts... criticism and better ideas are encouraged.

Subject: [lwip-users] Default lwipopts


There have been a fair number of queries to the mailing list recently
that have boiled down to the default lwipopts being unsuitable for
general usage.  They are set extremely conservatively, which might lead
people who are new to lwIP to think that the stack is at worst broken or
at best much lower performing than is the case.

I propose we provide two lwipopts configuration files:
- the first would be much like the current with an emphasis on low
memory footprint at the cost of performance.
- the second would have, for most people, what are more sensible
defaults allowing them to achieve much better performance.

Does anyone have any particular thoughts or suggestions on this?

Kieran
