How do I increase the connection concurrency of kdc? It is found that kdc processes are
blocked when the network traffic is heavy, but the physical resource usage of the server
is low.
1: Can you increase krb5kdc numworkers? I check that the default value is 32.
ps -ef | grep krb
....
/usr/sbin/krb5kdc -w 32 -P /var/run/krb5-kdc.pid
.....
The number of workers matches the number of CPUs by default.
# cat /etc/sysconfig/krb5kdc
man krb5kdc(8) for details
Running more workers will not necessarily improve concurrency as it may
well shift the load elsewhere.
2: kdc_max_tcp_connections Whether this configuration is valid, and
whether the number of UDP and TCP connections of the kdc is limited?How to make it bigger,
I looked up the relevant documents, but did not get the relevant documents clearly
explain.
Request guidance, thank you!
What relevant documents are those?
