The memory usage is a little too much to my concern

x64 ver. on my machine is around 25MB working set… would you do something to reduce the cost?

Thanks for your feedback. I trade memory for speed a lot in Listary. I’ll try to find a better balance.

P.S. Rams are so cheap now (less than $20 for 4G), I don’t think people will care about memory usage any more.

Yeah, please don’t trade speed for some minor and really not important memory improvements. For me it’s around 10mb and having 8gb or RAM it’s negligible.

Exactly - Working Set memory is irrelevant anyway - Private is quite small - this sort of concern largely died out with XP... Listary is not bloat. Do not sacrifice speed, please.
