Package: bash-completion Version: 1:2.8-4 Severity: normal Hi,
with the last upgrade of bash-completion completing hostnames has become slow (takes more than two seconds). My /etc/ssh/ssh_known_hosts file has quite some size (23084 lines / 12 MB), but this was not a problem with the previous implementation. I guess the problem is the while read … done < known_hosts_file loop, where the shell has to read() one byte at a time, causing a massive amount of syscalls (which have become even more costly this year).
