[lxc-users] CPU considerations

[Lars Hanke]

I'm going to migrate my OpenVZ based Core2 Quad SOHO server to a new 
hardware and LXC. The current hardware has more than enough performance. 
The new hardware shall be smaller and more energy efficient.

I'm currently pondering on i3-4130T and i5-4570S, but I fear the impact 
of the substantially smaller caches of the Haswells as compared to 
Core2. On the other hand cache misses may leverage the hyper-threading 
of the i3, i.e. might shadow the performance of the 4 physical cores of 
the i5.

As usual the only useful result is measuring, but I'm not going to buy a 
dozen systems. Does anyone have experience how LXC with roughly a dozen 
single service containers scales with CPU features?

Thanks for your experiences,
