Research direction
Start by locating text_multifile_backend and reviewing how it opens and closes files for each log record. Determine the cache behavior, most-recently-used policy, and idle timeout needed to reduce Windows open/close operations. Done means unused cached files are eventually closed while repeated logging reuses open files.
Written by the indexing model from the issue text.
Description
It was reported that on Windows file open and close operations are much more expensive than on other systems, e.g. Linux. This affects text_multifile_backend, which opens and closes a file on every log record.
Consider implementing a cache of the most recently used files, so that the amount of open/close operations is reduced. The cached entries should have a timeout as well, so that the file is eventually closed if it is not used for too long.
