Questions about VPS and benchmarking tools.
-
Hello, Many hosting companies are now offering virtual servers (called VPS). I am planning to book a VPS for one month to see if the performance are OK. To avoid writing a special application, are there ones that can be easily installed and that can perform benchmarking of the server ? My principal doubt is regarding two things: CPU frequency. Memory frequency. For the CPU, I'd like to verify if the frequency offered is real. So if an offer tells that a VPS will be given a 2.2 GHz CPU, I'd like an application to repeat the execution of some code for a long duration and then give idea of the execution speed and the evolution of that speed over time. I fear that the CPU is shared by some other applications on other VPS. Concerning memory, this is really very expensive. So for example 2 GB of RAM is the most that one can afford. However hosting companies tell that they provide SSD memory. So when swap occurs, it goes to SSD and not to the disk. I wonder if any benchmarking tool would be able to also test the performance of this SSD. I hope the tools in Linux. Thanks !
