Description

Due to compression default settings in debug, big tarballs can be very slow to create due compression. After taking a look at
https://catchchallenger.first-world.info/wiki/Quick_Benchmark:_Gzip_vs_Bzip2_vs_LZMA_vs_XZ_vs_LZ4_vs_LZO I want to change this a bit:

Today, foreman-debug tries to find compressors in this order (and options):

  • xz -9
  • bzip2 -9
  • gzip -9

This usually ends up with xz or bzip2 but both are remarebly slower with -9 option, so what I suggest now:

  • xz -1
  • bzip2 -1
  • gzip -5

Both xz and bzip2 are the same speed as gzip -5 and giving similar (slightly better) ratio.

Overall compression should be about 4 times faster after this patch.
