+# TCP Client (Master) Performance Analysis
+
+Analysis of the TCP client hot path focusing on read/write operations from user code through serialization, TCP I/O, deserialization, and response delivery.
+
+## 1. Sequential Request Processing (Largest Architectural Win)
+
+**Location:** `rodbus/src/client/task.rs:257-299` (`execute_request`)
+
+The current design processes exactly **one request at a time**: serialize → write → wait for response → parse → next. The full network round-trip latency is paid per request. For a typical polling application reading 20 different address ranges, this means 20 serial round-trips.
+
+Modbus TCP's transaction ID exists specifically to support pipelining. The code already matches on `tx_id` in the response loop (line 285-291), so the protocol-level plumbing is partially there.
+
+**Possible approach:** Allow N requests in-flight simultaneously. The `ClientLoop` would maintain a small map of `TxId → Request`, send multiple requests before waiting for responses, and match responses back by transaction ID. This could improve throughput by up to Nx where N is the pipeline depth, since you amortize the RTT across N requests.
+
+**Risk:** Some Modbus servers may not handle pipelined requests well. This would need to be opt-in.
+
+**Estimated impact:** High — removes RTT-per-request bottleneck.
+
+## 2. Double Heap Allocation Per Request (Box + Oneshot)
+
+**Location:** `rodbus/src/client/channel.rs:106-117`, `rodbus/src/client/message.rs:258-306`
+
+Every `Channel::read_*` / `Channel::write_*` call creates:
+1. A `tokio::sync::oneshot::channel()` (heap allocation)
+2. A `Box<dyn Callback>` wrapping a closure that captures the oneshot sender (heap allocation)
+
+So **2 heap allocations per request** just for the response plumbing. The `Promise<T>` type in `message.rs:258` boxes the callback unconditionally.
+
+**Fix:** Store a `PromiseInner` enum that can be either `Oneshot(oneshot::Sender<Result<T, RequestError>>)` or `Boxed(Box<dyn Callback<T>>)`. The `Channel` API would use the `Oneshot` variant directly, avoiding the Box. The `CallbackSession` (FFI path) continues to use `Boxed`. This removes one allocation from the Rust API hot path.
+
+Similarly, `rodbus/src/client/requests/read_bits.rs:17-19` and `rodbus/src/client/requests/read_registers.rs:20-22` have their own `Promise` types that also box unconditionally.
+
+**Estimated impact:** Medium — removes 1 heap allocation per request.
+
+## 3. Vec Allocation on Every Read Response
+
+**Location:** `rodbus/src/client/requests/read_bits.rs:69`, `rodbus/src/client/requests/read_registers.rs:72`
+
+```rust
+let _ = tx.send(x.map(|x| x.collect()));
+```
+
+Every read response allocates a new `Vec<Indexed<bool>>` or `Vec<Indexed<u16>>`. For polling applications that read the same register set thousands of times per second, this is a steady stream of allocations.
+
+**Fix options:**
+- Provide an API that accepts a pre-allocated `&mut Vec<Indexed<T>>` which gets cleared and refilled.
+- Provide an API returning an iterator over borrowed data (the `CallbackSession` already does this with `BitIterator`/`RegisterIterator` which are zero-copy, but the public `Channel` API forces the collect).
+
+**Estimated impact:** Medium — removes 1 heap allocation per read response.
+
+## 4. Tracing Span Per Transaction
+
+**Location:** `rodbus/src/client/task.rs:224-226`
+
+```rust
+.instrument(tracing::info_span!("Transaction", tx_id = %tx_id))
+```
+
+This creates a tracing span for **every** Modbus transaction. Even with no subscriber, the span creation and the `%tx_id` formatting (`Display::fmt` → `write!(f, "{:#04X}", self.value)`) have nonzero cost. At thousands of requests per second, this adds up.
+
+**Fix:** Guard the instrumentation behind the decode level check, or use `tracing::enabled!()` to skip span creation when no subscriber is active at the relevant level.
+
+**Estimated impact:** Low-Medium — saves formatting + span bookkeeping per request.
+
+## 5. Response Frame Copy
+
+**Location:** `rodbus/src/tcp/frame.rs:77-85` (`parse_body`)
+
+```rust
+fn parse_body(header, adu_length, cursor) -> Result<Frame, RequestError> {
+    let mut frame = Frame::new(header);  // zeroes 253 bytes
+    frame.set(cursor.read(adu_length)?); // copies payload into frame
+    Ok(frame)
+}
+```
+
+Every response:
+1. Zero-initializes a 253-byte `[u8; MAX_ADU_LENGTH]` array in `Frame::new()`
+2. Copies the response payload into it
+
+This could be avoided by having the response parser work directly from the `ReadBuffer` data (borrowing rather than copying). The `Frame` struct exists to own the data across the parse boundary, but the data is consumed immediately after in `handle_response`.
+
+**Estimated impact:** Low — saves 253-byte zero-init + payload memcpy per response.
+
+## 6. ReadBuffer Shift Logic Bug (Correctness)
+
+**Location:** `rodbus/src/common/buffer.rs:94`
+
+```rust
+if self.end == self.len() {
+```
+
+`self.len()` is `self.end - self.begin`. So this condition reduces to `self.begin == 0`, meaning the shift only triggers when data is already at the beginning (i.e., a no-op). The correct condition should be `self.end == self.buffer.len()` to detect when the write position has reached buffer capacity and consumed bytes at the front need to be shifted down.
+
+In practice this is benign for Modbus because the empty-check above resets indices between frames and responses typically fit in a single read. But it is a latent bug if a partial read leaves consumed bytes in the buffer.
+
+**Estimated impact:** N/A — correctness fix, not performance.
+
+## 7. ReadBuffer u16 Parsing
+
+**Location:** `rodbus/src/common/buffer.rs:68-72`
+
+```rust
+pub(crate) fn read_u16_be(&mut self) -> Result<u16, InternalError> {
+    let b1 = self.read_u8()? as u16;
+    let b2 = self.read_u8()? as u16;
+    Ok((b1 << 8) | b2)
+}
+```
+
+Two separate bounds-checked reads instead of one. Could read 2 bytes at once and use `u16::from_be_bytes()`. Very minor but this is in the frame parsing hot path (called 3 times per MBAP header).
+
+**Estimated impact:** Negligible.
+
+## Summary
+
+| # | Optimization | Type | Est. Impact |
+|---|---|---|---|
+| 1 | Request pipelining | Architectural | **High** |
+| 2 | Eliminate Box in Promise for Channel API | Allocation | **Medium** |
+| 3 | Reusable Vec / zero-copy read API | Allocation | **Medium** |
+| 4 | Conditional tracing span creation | CPU | **Low-Medium** |
+| 5 | Zero-copy response parsing (avoid Frame copy) | Copy | **Low** |
+| 6 | ReadBuffer shift condition fix | Correctness | N/A |
+| 7 | Batch u16 reads in buffer | CPU | **Negligible** |
+
+The dominant bottleneck is #1 (sequential processing). For a typical Modbus polling application with many address ranges, pipelining would dwarf all other optimizations combined since the cost is dominated by network RTT, not CPU.

+Valgrind provides deterministic, reproducible measurements that are independent of system load.
+
+### Instruction counts (callgrind)
+
+Measures total CPU instructions executed. Useful for detecting changes in serialization,
+parsing, and other CPU-bound code paths.
+
+```bash
+valgrind --tool=callgrind ./target/release/example-perf -s 1 -c 1
+```
+
+Produces a `callgrind.out.<pid>` file. Use `callgrind_annotate` to inspect:
+
+```bash
+callgrind_annotate callgrind.out.<pid>
+```
+
+### Allocation profiling (dhat)
+
+Counts heap allocations, bytes allocated, and allocation lifetimes per call site.
+Useful for verifying that allocation-reduction optimizations have the expected effect.
+
+```bash
+valgrind --tool=dhat --dhat-out-file=/tmp/dhat.out ./target/release/example-perf -s 1 -c 1
+```
+
+To view results, open `/usr/libexec/valgrind/dh_view.html` in a browser and load the output file.
