It does rather better on GnuCash files. I tried compressing my file,
"Accounts", with gzip and bzip2:
-rw-rw-r-- 1 gjditchf gjditchf 91604 Mar 31 08:13 Accounts.bz2
-rw-rw-r-- 1 gjditchf gjditchf 121615 Mar 31 08:13 Accounts.gz
-rw-rw-r-- 1 gjditchf gjditchf 1350319 Mar 31 08:13 Accounts
gzip took a snappy 0.765 seconds (300MHz K6-2); bzip2 took 9.5 seconds.
Every now and then someone on gnucash-devel suggests modifying GnuCash to let
it read and write gzipped files. Sounds good to me ...
I went looking for XML-aware compression schemes and found surprisingly
little. There's some alpha-level code at
and a paper there suggests that it wouldn't be hard to generate compressed
files that are half the size of the gzipped file.
