Orca Swap Latency Report.
Date: 2026-06-10 · Solana mainnet
Key Metrics
| Metric | Value |
|---|---|
| Full round-trip latency | 228ms |
| Validator-internal latency | 35.7ms (35,713µs) |
| Trigger mechanism | Tx 2 fires immediately on account update from Tx 1 |
| Slots spanned | 2 (425530152 → 425530153) |
| Pool | 9856759 · tick −27568 · spacing 1 |
Latency Breakdown
| Segment | Time |
|---|---|
| Validator internal (tx land → account visible) | 35.7ms |
| Full round-trip (bot → confirm → bot) | 228ms |
| Network + other overhead | ~192ms |
| Time from Tx 1 confirm to Tx 2 trigger | 39ms (7.894s → 7.933s) |
CatScope signal
The 35.7ms validator-internal latency is the CatScope signal: account state is visible via shared memory well ahead of RPC delivery.
Measurement Path
Bot → catfwd → Leader → Validator → Bot
Latency is measured from bot submission through catfwd, to the leader, processed by the validator, and back to the bot.
Transaction Results
| Direction | Tx | Slot | Result |
|---|---|---|---|
| SOL → USDC | Tx 1 | 425530152 | Success |
| USDC → SOL | Tx 2 | 425530153 | Expired |
Tx 2 was dispatched immediately upon receiving the account update from Tx 1. The failure was likely due to slippage — the quote was built off Tx 1's pre-confirmation state.
