Hum, they are not saying if they have the native part of JAI installed, in which output format they are encoding, if a server virtual machine is used... if none of the above is enabled, we're taking quite a hit. Nevertheless, if they are using 4 threads in parallel yeah, we might be seeing a stupid issue with reading synchronization. There are two options in the coverage config that need to be set in order to get better performance too, the tile size, and enabling the usage of the multithreaded readed, if you don't enabled them properly, you get a hit again. As I said to Simone already, some of those params (the tile size at least) should be guessed automatically because too often people don't even realize they are there.
