It went generally quick for me.

If it is networking, you may see some large amount of retrans (segment retrans, syn retrans, etc...) with `sar -n ETCP 1` while you are running the command. It could also be even before the TCP transmission, during the name resolution (generally UDP), see what `bpf-gethostlatency` tells you. Other tools like bpf-tcplife, or bpf-tcpconnlat can help to do some latency analysis.

This week I am experimenting long latencies when running

`fedpkg srpm`

(around 5 minutes, real time).

`strace -c fedpkg srpm` is telling me that the 'wait4' syscall is the one consuming most of the time (85%)

My network connection is not the fastest but running the rhpkg srpm I  basically got instant results.  Also, I am not sure if these delays started after the data center move but perhaps that may be a factor.

Any idea how to debug this one?
