Question

Ruby is truly memory-hungry – but also worth every single bit.

What do you do to keep the memory usage low? Do you avoid big strings and use smaller arrays/hashes instead or is it no problem to concern about for you and let the garbage collector do the job?

Edit: I found a nice article about this topic here – old but still interesting.

Answer 1

1. Choose date structures that are efficient representations, scale well, and do what you need.
2. Use algorithms that work using efficient data structures rather than bloated, but easier ones.
3. Look else where. Ruby has a C bridge and its much easier to be memory conscious in C than in Ruby.
