Hey people! I have two sites running on my Dell R630, 128GB ram, 2x 10 core xeons, on a 1GBPS network connection in a datacenter a few km from me. Ive got two sites running, both wordpress, both get very slow with traffic, with just like 20% cpu usage, network all good too. The server has 2x Mirror NVME drives, so i doubt the hardware would be the issue. The problem is mainly TTFB, the actual loading of stuff is "relatively" ok, altough not ideal either. We do get quite a lot of traffic, both sites have around 1-2k active users. We did not have any problems when on Google hosting, just the fact that the servers were pretty underpowered for their price in this case, with so many plugins, which is why we switched to our own hardware. Compared to google, it seems to get slow even when not using 100% of the CPU. Thats whats so odd. Any ideas? It only seems to be a problem when theres more traffic, like there isnt enough ports or something...thank you!!!
