CHR CPU Upgrade

Its been on my mind for a while that the CPU in my CHR wasn’t setting the world on fire, it was great for what it was doing and it was low powered but as I start and do more with my CHR, maybe start to look at a dude server and do some more advanced packet marking and processing I wanted something with more oomph!

I’ve now upgraded from a Xeon E3-1220L to an E3-1270. That’s a boost in base clock from 2.2Ghz to 3.4Ghz and a big step from 2c4t to 4c8t. I managed to do a small amount of testing before and after and whilst the difference from what has been done is negligible at this point, I’m expecting that as I burden the CPU more it will withstand the pressure for longer.

Before upgrade;

After CPU upgrade, same ESXi settings so this is “just” the core speed improvement;

This is the performance after shutting the machine down and applying the additional CPU cores;

 

Concluding my testing, a 400Mb increase in pushing traffic to itself from the CPU core speed upgrade, nothing to be sniffed at I guess, the traffic was also a bit more stable at this speed as opposed to the previous CPU.
