> We redesigned lazy mode, so that now it doesn't spawn new thread and has the same performance as old "eager" mode (IGNITE-9171). However, we didn't enable it by default because H2 1.4.197 contains several bugs causing query engine slowdown in some cases when lazy mode is set. These issues are resolved in H2 master and will become available as a part of the next release (presumably 1.4.198). 
> We need to make lazy mode enabled by default once new version is available (IGNITE-10801).
