Precision of `uniqid()` on Windows systems without passing `$more_entropy=true` has only single-second-resolution which will lead to non-unique ids on subsequent calls. In order to mitigate this issue TYPO3 provides the function `StringUtility::getUniqueId($prefix = '')` which calls `uniqid()` with parameter `$more_entropy` always set to true. Using `uniqid()`, especially with `$more_entropy` set to true, is quite slow, but for the purposes TYPO3 is using it (i.e. creating unique field names for backend forms, path identifiers in some modules etc.) it is good enough and another solution would not provide any measurable benefit.
