This document describes suggested feature options for optimizing Duktape
|

|
|
performance for performance sensitive environments.

Suggested feature options
|
||
|
|
=========================
|
||
|
|
|
||
|
|
* On some platforms ``setjmp/longjmp`` store the signal mask and may be
|
||
|
|
much slower than alternative like ``_setjmp/_longjmp`` or
|
||
|
|
``sigsetjmp/siglongjmp``. Use the long control transfer options to use
|
||
|
|
an alternative:
|
||
|
|
|
||
|
|
- ``DUK_OPT_UNDERSCORE_SETJMP``
|
||
|
|
|
||
|
|
- ``DUK_OPT_SIGSETJMP``
|
||
|
|
|
||
|
|
- On some platforms (e.g. OSX/iPhone) Duktape will automatically use
|
||
|
|
a faster alternative.
