I'm using MLDBM to store fairly complex data in a disk hash, up to 2,000 elements of stock data which comprise of about 20 peices of data per line. At the moment it nice and speedy on a tidy linux box.
My question is will the speed diminish as the volume of data increases to say 10,000 or possibly 50,000? Will it get to a point where reading the data is unbearable slow?
