hi all,

could any1 tell me about the performance issue with Https ? We have an application running on Http and Https, we need to display an jpg file at one stage of the application functionality. if it is https it works fine but if it is https for the image to be displayed it wll take atlast a minute. Could anyone tell me wat is the reason behind this..

any help on this is highly appretiated.

Thanks,
Rajeev.

HTTPS will always be slower than HTTP, there is nothing you can do about that, simply because there is more traffic for each request in HTTPS.

HTTPS does have an overhead, but nowhere near as much as one minute for an image (unless, maybe, the image is in the GB size range).
In my experience, if you have to worry about the performance difference between HTTP and HTTPS, we're talking about GBs of data per day. And if you're there, run, don't walk, to hire a performance expert, if you don't have one on staff already.

HTTPS data is encripted at the server and decripted at the client (Browser). This encription and decription takes a considerable time. And more over the data after encription becomes more in size. Thats why you are finding the delay.
