The lowest CPU has 4 cores or 4 threads nowadays. 2.2 GHz CPU (single core?) and 2 GB RAM sound more like a disposed PC. Why another computer, just for the exams?Īnd what is this 'server'.

You have a web cluster running Moodle already. Installing LAMP and Moodle doesn't take much time. So the most reliable thing in your case, just a single dedicated computer, running (RedHat?) Linux, is to do a test run.

But there are just too many parameters even to count, you need to be very lucky to find somebody who has a comparable set up and ready to run a test for you and submit the results. What you could get here is to listen to other people's experiences.

vnmi – Intel Virtual NMI feature which helps with certain sorts of interrupt events in guests.First of all you should realize that the question 'What hardware do I need for N concurrent users?' has no serious answer.

tpr_shadow and flexpriority – Intel feature that reduces calls into the hypervisor when accessing the Task Priority Register, which helps when running certain types of SMP guests.npt – AMD Nested Page Tables, similar to EPT.vpid – VPID, an Intel feature to make expensive TLB flushes unnecessary when context switching between guests.ept – Extended Page Tables, an Intel feature to make emulation of guest page tables faster.vmx – Intel VT-x, basic virtualization.Some important flags for sysadmins on Linux based system: # cpuid -1 | egrep -color -i 'aes|aes-ni' # cpuid -1 | egrep -color -iw 'vmx|svm|ept|vpid|npt|tpr_shadow|vnmi|flexpriority' # Is virtualization supported (see below for flags)? # # cpuinfo -k Search for specific CPU feature # cpuinfo -i Use the CPUID kernel module (not seems to be reliable on all combinations of CPU type and kernel version) # cpuinfo -1 Use the CPUID instruction (default and very reliable) Simply type the following command (this command provides lots of useful information including list of all features in human readable format):įig.02: Linux cpuid Command To Dump CPUID information Display information only for the first CPU
