I noticed transferring a large object or bytea data between client and server takes a long time. For example: An image with a real size of 11 MB could be read on server side (explain analyze) in 81ms. Fine. But on client side the result was completed after 6.7 seconds without ssl compression and 4.5 seconds with ssl compression (both via 100MBit ethernet). SSL compression seems to be not a good idea anymore, since this had become a security risk. Its still possible with pgadmin, but afaik not with java/jdbc . Are there any other solutions available to display my images in my client application more quickly? Or are there planned improvements to postgresql (transferring the real binary data)? Best regards Johannes
