Re: [Xen-users] Transcendent Memory ("tmem") -capable kernel now publicly released

hi  Dan.
        I  found a question that I canât understand when I test multi
tmem-aware VMs.
        I  run two VMs and use option "tmem_dedup" in dom0 to test dedup
between 2 clients.All the 2 VMs (vcpu=4,memory=256M) run "make Linux kernel"
operation. VM1 run first and after 3 minutes VM2 run. And VM1 end
workload(make Linux kernel)is 10 minutes earlier than VM2. The whole
workload last almost 3 hours . 

I found Tc(total_cycles) VM2 is almost double to VM1.
VM1's Tc(pre=468057722,post=769901743325),  so total_cycles is
769,433,685,603.
VM2's Tc(pre=551611474,post=1428367229662),so total_cycles is
1,427,815,618,188.
so VM2's all tmem-ops is double to VM1ïinclude "put" and "get". 
Are these statistics all right ??


Thanks a lot


Gavin
