Good day. We trying to test XCP cloud under some product-like load (4 hosts, each with 24Gb mem and 8 cores) But with just about 30-40 virtual machines I got an extreme load on dom0 on pool master host: LA is about 3.5-6, and most time are used by xapi and stunnel processes. It's really bother me: what happens on higher load with few thousands of VMs with about 10-16 hosts in pool... top data: Tasks: 95 total, 3 running, 91 sleeping, 0 stopped, 1 zombie Cpu(s):19.4%us,42.1%sy,0.0%ni,35.8%id, 1.3%wa, 0.0%hi, 1.0%si, 0.3%st Mem: 746496k total, 731256k used, 15240k free, 31372k buffers Swap: 524280k total, 128k used, 524152k free, 498872k cached PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 17 -3 315m 14m 5844 S 52.3 2.0 5370:41 xapi 17 -3 22524 15m 1192 S 8.3 2.2 875:16.18 stunnel 15 -5 0 0 0 S 0.7 0.0 54:28.78 netback 10 -10 6384 1868 892 S 0.3 0.3 22:03.14 ovs-vswitchd dom0 on non-master hosts are loaded about 25-30% each. _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
