I have a dedicated server 4.4GHz i7 with 4 cores and 8 threads.
Is it a good idea to run 4 heavy processes (each process eating ~80% CPU thread during peak load) per 1 dedicated server (hence 4 cores) and rent additional dedi for 5+ processes? 
Will I lose potential performance when running 5+ heavy processes on 4 core dedi?
It's worth mentioning that these are single threaded application(s).

Welcome to BC Courtney51!


So each of those 4 processes are eating 20% of the CPU while at peak load. Adding in an additional 5th process, assuming its similar will eat another 20%, putting you at max capacity of the CPU. I don't really see an issue with running those 5 on the same server. More than likely the peaks will fluctuate and they all won't hit at the same time. So you'll still have some room to spare. Of course if they go 100% all the time, you may want to use another server so you don't run the first one at full capacity all the time.

It all depends on what you are doing really. If you don't need any spare CPU cycles, running those 5 processes on one server should be fine. Again though, since I don't really know what you are running/doing (and may not be familiar with it) its hard to say. If it was me I would try it out on the one server, see how it works. If performance takes too much of a hit, move to a second dedicated server.


Hope that helps you out some!

Eh linux doesnt really force computers over the edge like windows does normally, it only uses what it needs to.

Microsoft windows eats up space, chews up ram and takes up power just because it can.

:inux uses things as it needs things.

Plus multitasking in general is far better in linux

Please note that this isn't a Linux versus Windows thread, but feel free to start one if you wish. :)
