Public bug reported:

I think that log files compression lowers the system performance on
desktop computers which have now enough disk space for storing old logs.

The "nocompress" and "compress" options of logrotate configure 2
different behaviours of logrotate.

If the log file isn't compressed,
logrotate will just rename it to something like 'log_file_name.log.1'
with quite no disk input/output.

If the log file is compressed,
logrotate will read the file, compress it and rewrite the content into a new file with a name like 'log_file_name.log.1.gz'.

I think that files compression is a good tradeoff only in case the
compressed files have a longer lifetime than the log files (i. e. man
pages, documentation, fonts, Debian package files, ...).

Drawbacks of log files compression :
- increases disk input/output
- increases cpu and memory usage
- increases energy consumption
- slightly decreases the disk lifetime
