VM website with 2-3 sites

I have a VM web server with 2-3 sites. Each site has it's own iP address but they are all on the same VLAN going to the same VSwitch. Currently all IP's are on 1 VNIC. Should I create separate VNICs for each IP/Site? Will that yield better performance?

Theoretically yes!

Yes, if you split the traffic into separate pipes....they will all then have 1GBe or 10GBe per network interface, depending on if you are using E1000 or VMXNET3.

And what about in reality? We used to run everything under 1 NIC

Depends how heavily loaded your Web Server is, specifications of the web server, current traffic levels, and where the bottleneck currently lives, network, CPU, Memory, Disk I/O ?

Also really depends if you want to segregate all the traffic, which would be a good idea.

Traffic isn't heavy, we have a 1 gig line and we are using about 300 megs per month.
You can have all sites on a single IP. it is called name-based virtual hosting and SNI

Thanks guys
As other have mentioned, the prefect setup is to have each site using its own IP and NIC. You can setup multiple sites to use one NIC/IP by separating the site using host headers: https://technet.microsoft.com/en-us/library/cc753195(v=ws.10).aspx

The questions to ask yourself are:
1) Are the VM's, host's NIC redundant?
2) Now much traffic you expect to get on each site?
3) Do you have to meet any compliance regulation that mandate isolating sites?
Sadly there are not enough IPs for your perfect setup. Nowadays virtual host support is absolute requirement to get any IP space.
