About the virtual host

[Yue Yuanyuan]

hi,
  I am using 6.0.28/centOS. After I edited the server.xml to add one virtual
host, it becomes extremely slow. And it got out of memory exceptions after I
deployed one project (20M size) on the the new virtual host.
  Is that possible two virtual host to use different memory space? Or how
could I have two tomcat instances running on the same server?
  Thank you.
best,
gavin
ps. this the my server.xml host setting:

      <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false">
