"* In `response_writer.go`, the `compressWriter.Write` method has a \"fast path\" that attempts to avoid buffering. However, this path is only taken if `w.buf == nil`. The buffer is only allocated when the \"fast path\" conditions are not met. This means that if the first `Write` call is small, a buffer is allocated and all subsequent `Write` calls will use the buffer, even if they are large. This is inefficient. I will refactor the `Write` method to be more efficient by removing the \"fast path\" and always buffering the initial writes until the minimum size for compression is reached. This will simplify the code and improve performance by reducing the number of `Write` calls to the underlying writer.\n* In `response_writer.go`, I will also simplify the `compressWriter.Flush` method. The current implementation has some complex logic to handle flushing the compressor and the underlying `ResponseWriter`. I will refactor it to be more straightforward.\n* In `adapter.go`, I will remove the `writerPool` and the associated logic for recycling `compressWriter` instances. The `compressWriter` will be allocated on demand and the garbage collector will be responsible for freeing it. This will simplify the code and reduce the chances of memory leaks.\n* In `adapter.go`, I will also remove the `bufPool` and the associated logic for recycling buffers. The buffers will be allocated on demand and the garbage collector will be responsible for freeing them. This will simplify the code and reduce the chances of memory leaks.\n* In `response_writer.go`, I will remove the `pool` field from the `compressWriter` struct and the `getBuffer` and `recycleBuffer` methods. The buffers will be allocated on demand and the garbage collector will be responsible for freeing them. This will simplify the code and reduce the chances of memory leaks.\n* In `response_writer.go`, I will remove the `compressWriterWithCloseNotify` struct and the associated logic.
