[infinispan-dev] MFC/UFC credits in default config

[Radim Vansa]

Sorry I haven't specified the amount, I am a stupido... my tests are working with 500k credits.

UUPerf (JGroups 3.2.4.Final-redhat-1) from one computer in perflab to another, 2 threads (default), 1000x sends 10MB message (default chunkSize = 10000 * our entry size is usually 1kB)  executed 3x

200k: Average of 6.02 requests / sec (60.19MB / sec), 166.13 ms /request (prot=UNICAST2)
      Average of 5.61 requests / sec (56.09MB / sec), 178.30 ms /request (prot=UNICAST2)
      Average of 5.49 requests / sec (54.94MB / sec), 182.03 ms /request (prot=UNICAST2)

500k: Average of 7.93 requests / sec (79.34MB / sec), 126.04 ms /request (prot=UNICAST2)
      Average of 8.18 requests / sec (81.82MB / sec), 122.23 ms /request (prot=UNICAST2)
      Average of 8.41 requests / sec (84.09MB / sec), 118.92 ms /request (prot=UNICAST2)
    
Can you also reproduce such results? I think that suggests that 500k behaves really better.

| What value would you like to use instead?
