Java ImageIO.write() takes up to 6 seconds

Question

I am writing an web application where I need to send an image from servlet to client. Image is generated dynamically and is quite big(+-2MB). It might be jpeg, png, or gif.<

Answer 1

Are you sure that the

ImageIO

takes so long - maybe there is another problem, e.g.

• slow (network) connection to the client
• the generation (calculation) of the image takes a lot of time
