Due to the recent fixes in CPSv, we are hoping the performance will be better than this. 1) Message size 1024 Bytes 2) Local reads performance is 5200 per sec 3) Local writes 4500 per sec So as you said , we don't see any problem in handling your specified traffic.

On 2 node cluster, question was what if checkpoint can handle certain traffic intensity (meaning how much processor load it causes): ~40 request per seconds for storing ~600 bytes data (~24 kBps). - call duration ~4 min - this results of ~ To me it sounds very low intensity so hope it should be no problem. We have not yet used CKPT and it will take some time to write small test program and get free HW to test it; so I am checking if you can at least provide some indication, if this intensity can easily be handled by CKPT service (and if you can roughly estimate corresponding load on some HW. HW could be an Pentium board (single-core) with let's say ~2GHz CPU).
