Strange, Murilo, I'm on Linux (Arch), and have never observed anything like that, from Java or otherwise.
For example, in https://code.google.com/p/commons-eid/source/browse/commons-eid-dialogs/src/main/java/be/fedict/eid/commons/dialogs/BeIDSelector.java the dialog is reading photos and names from electronic identity cards in parallel, as many as there are readers. Without this parallelism this dialog would become unfeasible with 2 or more readers since reading the photo takes several seconds, but the photos appear at about the same time, in 1.1 times the time required to read one photo. Tried this with 5 readers, should scale up much higher. This was also tested on various windows platforms, various Linux distros and OSX and works fine everywhere. Clearly parallellism works for me, as it should work for you. I don't have OpenSUSE handy to try this but I would think it highly improbable that they would have patched pcsc-lite to become an iterative server somehow. I'm guessing the serialization of your calls happens somewhere in your own code or Java rather than in pcsc-llite or the OS.. -f On 07/03/13 17:05, MURILO COSTA wrote: > Hello > > I have a Java system developed to record some smart cards and actually I am > using it on Windows, but now I am looking forward to switch it to Linux, > because some problems with USB smart card readers that I had, and to work > with it I am using the pcsc-lite, that works very well. > > But looking at some test results, I checked that the time of process on Linux > is greater than on Windows, and looks like the reason is because the > "parallel" process of windows, that doesn't happen on Linux when two or more > readers are used.
