I found a problem about sshd. My native linux:FC2, whose kernelversion is 2.6.16;My xen linux: the xen version is 3.0.2,dom0 whosekernel version is also 2.6.16. And the kernel configuration of nativelinux and xenlinux is similiar. Then I found that sshd(3.6.1p2) ranbetter on xenlinux(dom0) than on native linux. The connection time ofsshd on dom0 is about 20ms less than on native linux. Really? Or Ihave got a wrong result?

You're sure it's not a reverse DNS issue? SSH is *famous* for its delayswhen the reverse DNS of the connecting client is not enabled, and thenthe failure to find it winds up cached for a while.
