xTimeComposer-14: extremely slow launch (of a program)?

Post by jerryXCORE »

I am testing "example of simple web server" on xTimeComposer 13 and 14.1.0:
* It takes 14.8 seconds to launch the program on v-14
---(yes, I mean version 14.1.0, 14.0.x is even slower!!!)

* While it takes 3.7 seconds to launch the same program on v-13
---(I do modify the syntax of original program so that it can run on xTimeComposer-13)


Why is xTimeComposer-14 so slow?

(I like xTimeComposer-14, as it supports new syntax, which xTimeComposer-13 does not support)
(But I hate the slow building/launching process of xTimeComposer-14)

There are several changes between 13 & 14 that have affected build time.
There are plans to improve this in the future.

You may like to turn off whole program optimisation by adding to your makefile:
ENABLE_STAGED_BUILD=0
The downside is that your binary may be larger or slower.

Thanks, that improvement plan is definitely on my wish-list for new version.
