Management Studio & Localhost 1

[1DMF]

Hi,

Can someone confirm that if Management Studio is installed on the same server as the SQL instance, does it use the LAN to access it?

I was under the impression anything that accesses localhost loopback over TCP/IP does not go out across the network, the same for a browser accessing IIS on the same server via localhost IP's

Thanks,
1DMF.

If I am not mistaken, when it's on the same box, it uses shared memory if you have it configured that way. Shared memory is the fastest connection possible. Shared memory is enabled by default, but can be turned off in "SQL Server Configuration Manager".

In fact, according to that document, when connecting locally, it does use shared memory. You can force it to use tcp/ip or named pipes if you want, but you have to jump through a hoop or two to do it.

Thanks George, I didn't think the problems they were experiencing were LAN latency, and it turns out it wasn't.

It was log file growth going out of hand.
