Not quite true. A significant part of Nasal-related frame rate impact is caused by garbage collection. Its delay/jitter only depends on the number of Nasal objects and their references which need to be searched. Increasing the number of Nasal objects (code+data) existing in memory also increases the delay. The amount of Nasal code which is actually being executed only influences the g/c frequency, i.e. whether the effect is visible every few seconds vs several times per second. This is why we are loading large Nasal modules, like advanced weather, on demand only (= only when feature enabled). We're not unloading objects when disabling a feature though - this usually requires restarting fgfs. This should be remembered when comparing such features (i.e. restart fgfs after disabling advanced weather etc). cheers, Thorsten ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
