Basic configuration page lets you specify a directory on the disk where you will keep your SIL™ programs, the charset used to interpret those files, and the cache size of the SIL™ scripts.

SIL™ Cache Size is the length of the LRU that is necessary to keep already parsed trees in the memory. At runtime, the SIL Engine™ has already picked up the parsed and optimized tree from the memory, thus sparing some milliseconds and a disk access. Of course, it is good if all the trees are ready, but you should know that this comes at the cost of memory. If SIL™ is not used often on your install, you may choose to disable this cache, although we do not recommend it.


> ℹ️ The SIL Home Directory setting has been moved to the SIL Storage section of the Power Apps Configuration.
