| Description |
|
Looks like all the careful logic we had in 1.x releases where all read operations were getting CR locks was lost in 2.x conversion and now whenever we get a CW lock for WRITE openhandle caching, subsequent stats and other such operations would cancel it quickly negating the benefit. Need to convert most of the locks back to CR mode I guess. |
