Slow performance in DSM 4.2 on VMWare


Montago

Recommended Posts

I've constructed a pretty 'heavy' virtualization environment based on a Core i5 4670 with 16 GB RAM and 3x3 TB in Stripe mode (for testing)

 

Installed OS : Windows 7 pro x64 SP1

- VMWare Workstation 9

 

I've downloaded the DSM 4.2 that someone posted here on the forum, which is easy installable in VMWare Workstation.

 

Transfer speed:

Windows -> Windows : 100 / 100 Megabyte pr second (i'm maxing out the 1 Gbit LAN) :cool:

Windows -> Virtual DSM : 60 MB/s (Upload) :cry:

Virtual DSM -> Windows : 30 MB/s (Download) :evil:

 

This i horrible ... for LAN files... but i can live with those speeds for Cloudstation and maybe picture hosting...

 

I have a Synology DS409 Slim with 4x1TB in RAID 5 that gives me the same transfer speeds (horrible) ....

 

Does Synology simply suck at making File IO ??? or could there be something else wrong ?
