vFoglight Storage has a patch available that resolves this issue.  This problem was taken offline and the problem was identified. Version 1.6.1 will have this patch included and has fixed several performance issues.  Mike
Hello,  I'm running vFogStorage (v 1.6) on a VM (vSphere 4.1U1) with 2 vCPU's, 6GB RAM & 4 vDisk (on a Netapp array with 17x15K SAS disks). The VM itself is running fine but vFogStorage is extremely slow and becomes unresponsive for moments. I've tried using the console installed on the vFogStorage Server and also using it from a remote admin desktop. In both cases the console freezes randomly and after a while it resumes to respond, but when using from the remote admin desktop it's practically unusable as freeze periods are larger than on the local server.  It's possible to tune up the system to accelerate it?
vFoglight for Storage is extremely slow!!!
