Graphs from network monitors on my remote trading server

Here are some server monitoring graphs from my remote trading server. These graphs are produced by the server monitoring application, Munin. I ran both JForex and Metatrader 4 simultaneously on my server last week. The 512 MB of memory was noticeably insufficient. Which caused the system to use swap files, thus leading to I/O latency, and which held up the CPU. All of which are evident from the graphs below. This week I am only running JForex. The server load is within tolerable range. The thing with picking your own VPS is that no VPS provider is the same. You can't really compare just the numbers as there are just too many factors to be considered behind the scene on a VPS service. So it is important to run applications that you intend to run and stress your system in real-world conditions. If your system seems slow, figure out where exactly is the bottleneck before throwing away money for upgrades. This is where a server monitoring application comes handy.
