Klaus Post	87443af49e	Cache Windows mount point info (#8572) ... It seems like every upload creates a new StorageInfo object. This makes it very sensitive to slow code paths. A particular slow function is `IsLikelyMountPoint` on Windows since `windows.GetVolumePathName` is slow. We cache the result of this operation.

Harshavardhana	5e69a107d8	Support detecting mountpoints correctly (#7288) ... Currently windows support was relying on Symlink as a way to detect a drive, this doesn't work in latest Windows 2016, fix this to use a proper mechanism by using win32 APIs. Additionally also add support for detecting bind mounts on Linux.	2019-02-26 18:04:53 -08:00
Harshavardhana	25de775560	disable disk-usage when export is root mount path (#6091) ... disk usage crawling is not needed when a tenant is not sharing the same disk for multiple other tenants. This PR adds an optimization when we see a setup uses entire disk, we simply rely on statvfs() to give us total usage. This PR also additionally adds low priority scheduling for usage check routine, such that other go-routines blocked will be automatically unblocked and prioritized before usage.	2018-06-27 18:59:38 -07:00
