[Bug] Subgraph indexing very slow when block handler is used even if block handler's start block has not reached

[shiyasmohd]

Bug report

When this subgraph is deployed with block handler, subgraph is indexing very slow even if block handler's start block has not reached. When the data source with block handler is removed, subgraph is syncing much faster.
