swx explorer painfully slow

We are using solidworks explorer in conjunction withworkgroup pdm and it is painfully slow. So far I have triedexempting all solidworks files and folders from our antivirussoftware, workgroup pdm has search/indexing enabled and as far as Ican see(using task manager) network bandwidth is not exceeding>1%.

I have also noticed that accessing files through the pdm task panecan take some time as well although, it is not as bad as explorer.

any help would be appreciated.SolidworksSolidworks Explorer
