perf(flamegraph): regenerate artifact after order-book/network changes#139
Conversation
Refreshes the committed flamegraph so its Source digest matches current src/ (PRs #136 #137 #138; Dirty inputs: no). The try_emplace optimization (#138) is visible: the previously top-3 std::_Rb_tree::_M_emplace_unique allocation frame (~1137 samples) is gone from the hot stacks, which are now the actual matching work — cancel, match_baseline, rest, new_limit. ~20k samples, zero [unknown].

Warning Review limit reached
More reviews will be available in 2 minutes and 10 seconds. Learn how PR review limits work. Your organization has used up its prepaid credits, and credit purchases are no longer available. Enable the review add-on in the billing tab to keep reviews running — you're only billed for reviews past your plan's rate limits ($0.25/file). ⌛ How to resolve this issue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based credits. 🚦 How do rate limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

The
try_emplaceoptimization (#138) is visible in the profile: the previously top-3std::_Rb_tree::_M_emplace_uniqueallocation frame (~1137 samples — the redundant price-level map node alloc/free) is gone from the hot stacks. The hot path is now the actual matching work —cancel,match_baseline,rest,new_limit— rather than allocation overhead.Notes
