Compression ratio and time for common tools

One application I’m working with produces horrendous amounts of log files. They are so large that the process of compressing them and moving them to another server actually has a performance impact on the system in spite of nice and ionice. I decided to compare the most common compression tools. At home I’m using bzip2, as I want the best possible compression ratio. Would that be a good idea?

Compression ratio and time

As the table shows bzip2 is frightfully expensive, but it does produce small files. In addition it makes a big difference if gzip is told to optimize for speed (1) or compression (9), or if it runs at the default level (6). Compress is basically an outdated tool and was included as it is sometimes quoted as being faster than gzip. Here that was not the case.
