This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
I have a online site where on clicking a button I update a file. Also, on opening the page I read values from the file. Then on clicking the submit button at the end of page I write to the file. Users who are going to access this site are not very high. Will there be a performance issue when many are accessing the ssame page.
Let me know what else I can do to increase performance.
