--------------------------------------------------------

Tested perf with UPerf (measures throughput and latency)
Environment:
- JGroups master (3.5) with JGRP-1767 and JGRP-1768 included
- cluster-xx lab, 1Gbps network (~125MB/sec)
- 8 nodes: cluster01-08
- fast.xml (attached) with ip_ttl=1 *and queue for OOB thread pool*
- Each node invokes 20'000 RPCs: 80% sync GETs and 20% async PUTs
- numOwners=2

- Configs are:
|| A || B || C ||
| ignore_dont_bundle=false | ignore_dont_bundle=true | ignore_dont_bundle=true|
| {{+DONT_BUNDLE +OOB}} | {{+DONT_BUNDLE +OOB}} | {{-DONT_BUNDLE -OOB}} |



The results are (in avg. requests / sec / node):

|| Invoker threads || SSWT (A) || SSWT (B) || SSWT (C) || TQ (A) || TQ (B) || TQ (C) || SS (A) || SS (B) || SS (C) ||
|   1 | 4754 | 4545 | 23 | 4809 | 4415 | 4647 | 4698 | 4718 | 4656 |
|   4 | 14699 | 14033 | 74 | 15122 | 13864 | 14079 | 15715 | 14275 | 13782 |
| 10 | 22948 | 21192 | 227 | 23232 | 22576 | 22312 | 22487 | 21920 | 18403 |

> In Radargun benchmark of JGroups mimicking the behaviour of Infinispan we can see that performance with bundling on actually reduces the performance.
> See attached configurations and results.
