[infinispan-dev] TransactionTable concurrent maps and concurrency levels

The two concurrent maps (for local and remote transactions) use default concurrency levels. Should these be tuneable in <transaction …>, and either way, what should they default to? I really don't think the JDK default (16!) is nearly good enough. I have a benchmark that runs 250 threads and this causes a lot of blocking on these maps. How about <locking concurrencyLevel … > as the default for these maps? Is that good enough in terms of a config parameter, or do we want finer-grained control?
