## cache
Gets, or when options are provided sets, the limits of _libvips'_ operation cache.
Gets or, when options are provided, sets the limits of _libvips'_ operation cache.
Existing entries in the cache will be trimmed after any change in limits.
This method always returns cache statistics,
useful for determining how much working memory is required for a particular task.
**Parameters**
- `options` **([Object](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object) \| [Boolean](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Boolean))** Object with the following attributes, or Boolean where true uses default cache settings and false removes all caching.

- `options.memory` **[Number](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number)** is the maximum memory in MB to use for this cache (optional, default `50`)
- `options.files` **[Number](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number)** is the maximum number of files to hold open (optional, default `20`)
- `options.items` **[Number](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number)** is the maximum number of operations to cache (optional, default `100`)

the number of threads _libvips'_ should create to process each image.
The default value is the number of CPU cores.
A value of `0` will reset to this default.
