bpf_timer memory utilization

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,
Using BPF Hashmap with bpf_timer for each entry value and callback to
delete the entry after 1 minute.
Constantly creating load to insert elements onto the map, we have
observed the following:
-3M map capacity, 1 minute bpf_timer callback/cleanup, memory usage
peaked around 5GB
-16M map capacity, 1 minute bpf_timer callback/cleanup, memory usage
peaked around 34GB
-24M map capacity, 1 minute bpf_timer callback/cleanup, memory usage
peaked around 55GB
Wondering if this is expected and what is causing the huge increase in
memory as we increase the number of elements inserted onto the map.
Thank you.
