After taking a second look, there appears to be more to this then just vm configuration. I set up the latest svn's for the ide and compiler on a well provisioned VirtualBox 2.1 vm running Fedora 10 and am seeing the same issue that the original poster described. Doing anything form related, such as dropping a new component or moving an existing one drives the cpu into saturation for many seconds. During that time, click events are dropped, form repaints aren't done and the process activity seems evenly divided between the ide and X. The huge Netbeans and Eclipse ide's run acceptably fast on this vm, so this issue isn't due to a lack of computing resources. Trying to narrow it down, I removed all the Virtualbox guest extensions, went back to the generic vesa driver, toggled hvm support and tried running the ide as root... all with the same result. The same ide and compiler svn's run fine on a bare metal install of Fedora 10. This is the first time I've seen an application that didn't run perfectly under VirtualBox and I'm curious what the underlying problem is. I'm planning to set up oprofile when I have some time to see where all those cpu cycles are going. If anyone has additional suggestions for troubleshooting this, I'll be happy to try them.
