Under certain circumstances, the filesystem cache can be put under pressure due to cache evictions cause by log4j-sniffer opening and reading many files.
To alleviate this, we can support the use of O_DIRECT
on linux systems, and equivalent features of other operating systems that allow for reading of files without the use of the filesystem cache.
