Currently, the ticketing site is able to handle about 1.2 lakh concurrent connections on web servers and can book about 2000 tickets per minute.
"We have upgraded the system with high capacity servers to book more tickets. Earlier our capacity was to book about 1200 tickets per minute but now it has been enhanced to 2000 tickets per minute and it will be further increased to 7200," said a senior IRCTC official.
He said with the continuous upgrading, an average booking per day has been increased from 3.67 lakh in 2012 to 4.15 lakh now.
Former Railway Minister Pawan Kumar Bansal had announced in his Rail Budget 2013-14 that the booking capacity will be enhanced to 7200 tickets per minute with the development of next generation software for the e-ticketing site.
Railways have earmarked about Rs 100 crore to upgrade the ticketing website to meet the growing demand of e-tickets.
Generally there is a huge load on the website at 10 am, when booking of Tatkal tickets opens. The booking of ticket varies from time to time based on festival and vacations.
