In your experience, what is the best web programming language used to handle sorting and comparison of very large lists (ie tens of thousands of email addresses)?
I am most familiar with PHP. I think that it could get the job done, but I’m unsure of other languages and if there might be a bettor suitor.
Thanks!
I would store the emails in a database, and use SQL to perform sorts and searches. That is what databases were designed for, and they will have intelligent solutions that will outperform anything most people could write in code.
