[fitsbits] Rice compression from the command line
On Tue 2006/07/18 16:42:28 MST, Rob Seaman wrote in a message to: I now mostly use bzip2 (GPL, bzip.org), it usually outperforms gzip by about 10% for binary data. It's quite a bit slower, however. Of course, it does depend on the type of binary data - pure random data should not be compressible. I measured the 10% figure for the FLC animations distributed from my web site. If the files are intended for download, especially very large files, the extra time taken to compress/uncompress them is more than compensated by the faster download time. Mark Calabretta ATNF |
