Timing sensitive environments
Timing sensitive environments include e.g. games. In these environments long blocking times are problematic. Stop-and-go garbage collection is also a potential issue.
This document describes suggested feature options for reducing Duktape latency in timing sensitive environments.
The following genconfig option file template enables most timing
sensitivity related options:
Suggested feature options
- Use the default memory management settings (reference counting and
mark-and-sweep) but disable
DUK_USE_VOLUNTARY_GCto eliminate mark-and-sweep pauses. Use explicit GC calls (either
duk_gc()from C or
Duktape.gc()from ECMAScript) when possible to collect circular references.
