in reply to Fast data structure..!!!

I see only four options for you:
  1. Buy a faster computer
  2. use an array, not a hash (if your data really is numerical & sequenced)
  3. Code it in C
  4. Live with it
Here's some timings on my computer (Linux, Perl 5.8.8, AMD Dual core 4800)
use Time::HiRes qw/time/; my $start = time; my %save; for(0 .. 2000000) { $save{$_}{$_+1}=$_+2; } print "hash: ", time - $start, "\n"; $start = time; my @save; for(0 .. 2000000) { $save[$_]{$_+1}=$_+2; } print "array: ", time - $start, "\n"; #Ouput: #hash: 4.92373299598694 #array: 3.34077191352844

[choroba]: Yeah, let's ban dot in INC, but add glob to it!
[Corion]: choroba: Well, at least the above is user-defined, not implicitly by Perl ;)
