Virtualization Performance: Linux VMs on ESXi
We introduced our new vApus FOS (For Open Source) server workloads in our review of the Facebook "Open Compute" servers. In a nutshell, it a mix of four VMs with open source workloads: two PhpBB websites (Apache2, MySQL), one OLAP MySQL "Community server 5.1.37" database, and one VM with VMware's open source groupware Zimbra 7.1.0. Zimbra is quite a complex application as it contains the following components:
- Jetty, the web application server
- Postfix, an open source mail transfer agent
- OpenLDAP software, user authentication
- MySQL is the database
- Lucene full-featured text and search engine
- ClamAV, an anti-virus scanner
- SpamAssassin, a mail filter
- James/Sieve filtering (mail)
All VMs are based on a minimal CentOS 6 setup with VMware Tools installed. All our current virtualization testing is on top of the hypervisor which we know best: ESXi (5.0). We have changed two things in our vApusMark FOS setup: we upgradeded the guestOS from 5.6 to 6.0 and increased the number of vCPUs of the OLAP VM from 2 to 4. This small upgrade means that our latest results should not be compared to the results in our older articles.
We (Tijl Deneut and myself) tested with four tiles (one tile = four VMs). Each tile needs nine vCPUs, so the test requires 36 vCPUs.
The benchmark above measures throughput. As for response times, let's take a look at the table below, which gives you the average response time per VM:
| vApus FOS Average Response Times (ms), lower is better! | ||||||||
| CPU | PhpBB1 | PHPBB2 | MySQL OLAP | Zimbra | ||||
| AMD Opteron 6276 2.3 | 671 | 514 | 1410 | 758 | ||||
| AMD Opteron 6174 2.2 | 674 | 524 | 1210 | 861 | ||||
| Intel Xeon E5-2660 2.2 | 645 | 394 | 160 | 631 | ||||
| Intel Xeon E5-2690 2.9 | 362 | 288 | 40 | 483 | ||||
| Intel Xeon X5650 2.66 | 745 | 569 | 821 | 866 | ||||
Considering that we may assume that the Xeon E5-2690 consumes considerably more than the E5-2660, it looks like the Xeon E5-2660 is the new virtualization champ. Let us check out the power consumption numbers under a realistic load.

But capping smartphone market hits them most on component suppliers. Sony reported a quarterly loss because of low demand for image sensors used on smartphones. And Sharp is among the Asian suppliers who have recently complained of a decline in demand for components for smart phones.http://www.gpsphone-tracker.net/
