I wanted to build an awesome place for people to discuss module specific issues, but I don't have any more time for this, and there are much better places to discuss Perl-related issues. I'd recommend asking your question on Stack Overflow or on Perl Monks.
If you are looking for a Perl tutorial or Perl-related news, I hope these links will serve you well.

response time
This module is very much something I've been looking for, but the following three line script --
use Finance::QuoteOptions; my $q=Finance::QuoteOptions->new('DIA'); die 'Retrieve Failed' unless $q->retrieve;

takes over 10 seconds to run on my system. The README states that a Yahoo option chain takes about 1 second. What could be making my response so slow?

Re: response time
The response time is very dependent on Yahoo and your internet connection. Although I saw 1 second while writing the module, my own response time has varied widely. Unfortunately, those variables are out of my control. Kirk

Re: response time
Thanks. Actually DIA is probably the worst case. I'm finding others faster.

I've been "scraping" the Optionetics site for options chains. They have all expirations on one page, so it's been reasonably fast. I've been getting About 4300 stocks, 238,000 options in less than an hour. I just want closing prices so once per day is fine.

Unfortunately Optionetics data is bad and getting worse. I'm hoping this module will get me back on track.

Re: response time
currently i scan entire AMEX,NYSE,NASDAQ stock exchanges and grab all available option chains in 30 minutes or less on 512/256 adsl1 so i would be inclined to say that bandwidth might be a problem but i would dare to say that it is not your only problem
