Why is there no load on the server?

Question

System administration

Listen, I encountered such a strange thing, there is an application on the server that runs in 124 threads (WS client)
Listens to data, performs not at all complicated processing (array search with 4 if) and stores them in memcache

When I turn on htop, I see a horse load Load average as in data center, usually when I see this, the josco server slows down and it’s not possible to do anything on it at all, but not here, a completely different picture, all programs work properly, there are no brakes at all, the responses are good, everything is ok, and to be honest with me frightens, well, how is it that with such a Load average I don’t feel any changes? this is normal? why is this happening? unless the computer should not make bricks?

Answer 1

Load Avg is growing for various reasons.
As a rule, lags during Load Avg are caused by slow read / write operations (to disks and / or over the network).
In your case, it grows due to the load on the processor not related to read / write operations, so there are no lags

Answer 2

install iotop and watch
