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 ProblemType: Bug DistroRelease: Ubuntu 11.04 Package: jockey-common 0.9.2-0ubuntu5 ProcVersionSignature: Ubuntu 2.6.38-11.48-generic 2.6.38.8 Uname: Linux 2.6.38-11-generic x86_64 Architecture: amd64 CurrentDmesg: [ 26.629307] ISO 9660 Extensions: Microsoft Joliet Level 3 [ 26.706653] EXT4-fs (sda1): re-mounted.
