title: S3Fs directory listings slow - caching somehow possible?
body: <p>I'm wondering if there is any way to practically speedup directory listings of a s3fs mount? I have a WebDAV server, only for read operations, that basically access my s3fs mount. The problem is that listing directories is slow, while transfer speed is fine.</p>
  <p>So I started to look a bit around the web a stumbled across &quot;JuiceFS&quot;, sadly this was also not an option for several reasons. Then I tried &quot;vmtouch&quot; to index the mounted s3 storage to local memory, this is also not working as it's a shared resourced managed by the fuse kernel extension.</p>
  <p>Even using S3FS built-in cache does not solve the issue, instead it makes it even worse as the file first getting downloaded from s3 into the cache locally and then served via WebDav ...</p>
  <p>Is there no way to just speedup directory listing using S3? Basically, this is all I need in the end and no fancy POSIX compatible Block Device like JuiceFS which basically creates its own logic on top of your s3 bucket ... Not what I was searching for.</p>
