I was trying to figure out why my gallery 2 site is so slow on Dreamhost tonight, and noticed that Dreamhost puts your home directory on a NFS fileserver.
What really surprised me was to find the server network interfaces running at 100BT. This of course would really slow down NFS performance to the file server where my data is located.
eth0: Link is up at 100 Mbps, full duplex.

Of course, this is going to make NFS traffic to the file server very slow, yet the NIC is a Gigabit NIC

So…
Whats up Dreamhost? Gigabit switches are the standard in datacenters now, and have been for a while. Why haven’t you upgraded your switches ?
