I have two servers exactly identical. Same CPU, same ram, same HDD, same ISP.
Once is giving me 1300 H/s and the other one is 4300 H/s

Server1
[2020-04-13 15:28:33.072] speed 10s/60s/15m 1287.2 1370.7 1374.7 H/s max 1440.7 H/s

Server2
[2020-04-13 15:29:02.897] speed 10s/60s/15m 4397.6 4414.0 4384.7 H/s max 4607.8 H/s

Both servers are showing this when startig :

Any idea why such H/s difference in the two servers?

That doesn't seem right. Are you sure you are starting them with the same command/script from the same operating system? I guess you have ubuntu, plz check with "htop" for the CPU load.

btw: some tipps for xmrig:

use the number of physical threads your System has, which is 12 (2x6), not 24
for slightly better performance enable "hugepages" in your system or start the miner as root (xmrig can configure RAM itself)
for even better performance you could enable "1GB-hugepages" (just google xmrig 1gb-hugepages ubuntu), but this would require a lot more RAM than you currently have (at least 40 GB)

Thanks for the Tips. With hugepages enabled and 12 threads Im getting some more H/s. But I still have a huge difference between the two identical servers. Both running the same command. And htop shows 99-100% CPU utilization in both servers.... Very strange....

EDIT:
With 12 cores and hugepages enabled, the difference is even bigger:

Server1:
[2020-04-14 11:07:12.505] speed 10s/60s/15m 1655.8 1657.6 1654.0 H/s max 2204.9 H/s

Server2:
[2020-04-14 11:05:46.498] speed 10s/60s/15m 6188.6 6223.6 6235.3 H/s max 6273.5 H/s

Any idea what I can check? As said, both servers are showing 12 cores at 100% cpu utilization. (htop)
