> {color:#172b4d}This is based on a pure lookup test done based on "warp" client ([https://github.com/minio/warp).] Lookup test can be performed via "stat" option in warp.{color}
> *Issue:*
> *=====*
> OM's getBucketInfo(), infoVolume(), listKey() etc internally makes use of {{{}checkAcl{}}}.
> This internally uses "getVolumeOwner()" acquiring and releasing locks. Some of these getBucketInfo, infoVolume() information can be cached locally instead of locking/releasing everytime to substantially reduce lock contention. If needed, it can be invalidated after sometime.
