hi, change the COMPRESSION variable to lz4 ou lzop in your /etc/mkinitcpio.conf : it will considerably reduce the compression time. grep COMP /etc/mkinitcpio.conf # COMPRESSION #COMPRESSION="gzip" #COMPRESSION="bzip2" #COMPRESSION="lzma" #COMPRESSION="xz" #COMPRESSION="lzop" COMPRESSION="lz4" # COMPRESSION_OPTIONS #COMPRESSION_OPTIONS=() see here <https://catchchallenger.first-world.info/wiki/Quick_Benchmark:_Gzip_vs_Bzip2_vs_LZMA_vs_XZ_vs_LZ4_vs_LZO> for quick benchmarks... regards, lacsaP.
