If it's just 30,000 items then Marshal or PStore might do as well.  If
the whole data set easily fits into memory that would probably be the
easiest choice.  Sample:

$ time ruby -e 'h={};30_000.times {|i|
h[i]=10.times.map(&:to_s)};t=Time.now;File.open("x","wb"){|io|Marshal.dump(h,
io)};puts(Time.now-t)'
0.3430196

real    0m0.597s
user    0m0.452s
sys     0m0.124s

Kind regards

robert
