      Description

      Discussion started in SERVER-16665. WT supports multiple eviction threads but uses only 1 checkpoint thread. Both eviction and checkpoint threads can do compression when compression is used for a collection/index so more threads for checkpoint is likely to reduce write stalls during slow checkpoints. The wt_perf.c benchmark client uses more than 1 checkpoint thread, so I assume that is supported for WT.
