hcache | showing top X biggest cache files | Caching library

hcache is a Go library typically used in Server, Caching, Nodejs applications. hcache has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

The pcstat tool can get page cache statistics for one file by the file's name, or all cached files for a process by the process's pid. However, I often meet with a question: I know os cached memories by cat /proc/meminfo or free, but I can't find out those BIG files which is being cached. Of course I can use the ps aux command to get those processes who used a lot of memory and get the details by the pcstat --pid [pid], but pcstat does not sort the result, and it is not convenient. So I add a feature to pcstat: you can use the option --top [X] to show the top X biggest cached files globally. After that, you can use lsof to find out the bad guy.
