// static const int kL0_SlowdownWritesTrigger = 8;
static const int kL0_SlowdownWritesTrigger = 16;
// static const int kL0_StopWritesTrigger = 12;
static const int kL0_StopWritesTrigger = 64;
+ db/version_set.cc
//static const int kTargetFileSize = 2 * 1048576;

static const int64_t kMaxGrandParentOverlapBytes = 20 * kTargetFileSize;
