Hi, I am looking at our configuration of the Ignite checkpointing system to ensure we have it tuned correctly.
There is a checkpointing thread pool defined, which defaults to 4 threads in size. I have not been able to find much of a discussion on when/how this pool size should be changed to reflect the node size Ignite is running on. In our case, we are running 16 core servers with 128 GB RAM with persistence on an NFS storage layer. Given the number of cores, and the relative latency of NFS compared to local SSD, is 4 checkpointing threads appropriate, or are we likely to see better performance if we increased it to 8 (or more)? If there is a discussion related to this a pointer to it would be good (it's not really covered in the performance tuning section). Thanks, Raymond. -- <http://www.trimble.com/> Raymond Wilson Trimble Distinguished Engineer, Civil Construction Software (CCS) 11 Birmingham Drive | Christchurch, New Zealand raymond_wil...@trimble.com <https://worksos.trimble.com/?utm_source=Trimble&utm_medium=emailsign&utm_campaign=Launch>
