Parallel TxFrame creation: Creates TxFrames from XDR envelopes in parallel during transaction set deserialization. Uses work-stealing via std::async with even distribution across available threads. 2. Parallel transaction validation: Validates transactions in parallel in txsAreValid() when there are 2+ transactions. 3. Hash precomputation: Precomputes content and full hashes before parallel operations to avoid race conditions. 4. Test coverage: Adds StreamingShaTest for InvokeHostFunctionSuccessPreImage verification.

Added getInMemorySorobanStateForUpdate() to allow direct access to mInMemorySorobanState during COMMITTING phase. This reduces ledger close latency by overlapping CPU-bound operations. # Conflicts: # src/ledger/LedgerManagerImpl.cpp --- .../results.csv | 7 ++ bench/parallel_finalize-20260411-004339/stamp | 61 +++++++++++++++++ src/ledger/LedgerManagerImpl.cpp | 67 +++++++++++++++++-- src/ledger/LedgerManagerImpl.h | 4 ++ 4 files changed, 134 insertions(+), 5 deletions(-) create mode 100644 bench/parallel_finalize-20260411-004339/results.csv create mode 100644 bench/parallel_finalize-20260411-004339/stamp diff --git a/bench/parallel_finalize-20260411-004339/results.csv b/bench/parallel_finalize-20260411-004339/results.csv new file mode 100644 index 000000000..7bc5246cc --- /dev/null +++ b/bench/parallel_finalize-20260411-004339/results.csv @@ -0,0 +1,7 @@ +scenario,median_time_ms,p95_time_ms,p99_time_ms +"sac,TX=3200,T=1",305.0832699999992,328.24081280000155,345.8619323500045 +"sac,TX=3200,T=8",200.85186199999998,223.70137944999925,239.71351545000005 +"custom_token,TX=1600,T=1",295.2982734999987,318.2537639500033,325.8576103299988 +"custom_token,TX=1600,T=8",128.07441999999992,140.2383675499988,146.07508058000235 +"soroswap,TX=1000,T=1",443.2655024999949,474.08573100000024,493.5304318800002 +"soroswap,TX=1000,T=8",147.80120100000022,160.15533555000002,171.82685714000084 diff --git a/bench/parallel_finalize-20260411-004339/stamp b/bench/parallel_finalize-20260411-004339/stamp new file mode 100644 index 000000000..fd0f2e1aa --- /dev/null +++ b/bench/parallel_finalize-20260411-004339/stamp @@ -0,0 +1,61 @@ +Warning: running non-release version v26.0.0-79-gea3e26a10 of stellar-core +v26.0.0-79-gea3e26a10 +ledger protocol version: 26 +rust version: rustc 1.88.0 (6b00bc388 2025-06-23) +soroban-env-host versions: + host[0]: + package version: 21.2.2 + git version: 7eeddd897cfb0f700f938b0c8d6f0541150d1fcb + ledger protocol version: 21 + pre-release version: 0 + rs-stellar-xdr: + package version: 21.2.0 + git version: 9bea881f2057e412fdbb98875841626bf77b4b88 + base XDR git version: 70180d5e8d9caee9e8645ed8a38c36a8cf403cd9 + host[1]: + package version: 22.0.0 + git version: 1cd8b8dca9aeeca9ce45b129cd923992b32dc258 + ledger protocol version: 22 + pre-release version: 0 + rs-stellar-xdr: + package version: 22.0.0 + git version: 715003372ea6380044b5a4a02907ff73e56ae9e7 + base XDR git version: 529d5176f24c73eeccfa5eba481d4e89c19b1181 + host[2]: + package version: 23.0.0 + git version: 688bc34e6cd15c71742139e625268c7f30f55a92 + ledger protocol version: 23 + pre-release version: 0 + rs-stellar-xdr: + package version: 23.0.0 + git version: e83a6337204ecfdb0ac0d44ffb857130c1249b1b + base XDR git version: 4b7a2ef7931ab2ca2499be68d849f38190b443ca + host[3]: + package version: 24.0.0 + git version: a37eeda815e626f416eff13f2eacb32a8b0c3729 + ledger protocol version: 24 + pre-release version: 0 + rs-stellar-xdr: + package version: 24.0.0 + git version: 07b765d3ab146f7f7ea951af1f9e41e0ece8fb48 + base XDR git version: 4b7a2ef7931ab2ca2499be68d849f38190b443ca + host[4]: + package version: 25.0.0 + git version: 6323c1fc03ecb9f53b7c1e42fd62c1bbd3aebc2c + ledger protocol version: 25 + pre-release version: 0 + rs-stellar-xdr: + package version: 25.0.0 + git version: dc9f40fcb83c3054341f70b65a2222073369b37b + base XDR git version: 0a621ec7811db000a60efae5b35f78dee3aa2533 + host[5]: + package version: 26.0.0 + git version: b351f88a468d3b9e1d6de53d5b0ca585f6b7dadb + ledger protocol version: 26 + pre-release version: 0 + rs-stellar-xdr: + package version: 26.0.0 + git version: dd7a165a193126fd37a751d867bee1cb8f3b55a6 + base XDR git version: cff714a5ebaaaf2dac343b3546c2df73f0b7a36e + +Benchmark ledgers=200 \ No newline at end of file diff --git a/src/ledger/LedgerManagerImpl.cpp b/src/ledger/LedgerManagerImpl.cpp index 03cb9fc98..840f54153 100644 --- a/src/ledger/LedgerManagerImpl.cpp +++ b/src/ledger/LedgerManagerImpl.cpp @@ -75,6 +75,7 @@ #include "LedgerManagerImpl.h" #include +#include #include #include #include @@ -250,6 +251,14 @@ LedgerManagerImpl::ApplyState::getInMemorySorobanState() const return mInMemorySorobanState;

OpenSSL automatically uses SHA-NI, providing 4.6x speedup for streaming add() (893ns->193ns/call) and 56% total SHA256 self-time reduction (3,744ms->1,659ms per 30s trace). Use opaque aligned storage for SHA256_CTX in the header to avoid naming conflict between OpenSSL's ::SHA256 function and stellar::SHA256 class.

implementation +(Colin Percival hash_sha256_cp.c), despite running on Intel Xeon Platinum 8375C +(Ice Lake) which supports SHA-NI hardware instructions. OpenSSL 3.0.2 +automatically uses SHA-NI when available, providing 2-5x speedup. Switching the +SHA256 backend from libsodium to OpenSSL should save ~2,000ms of self-time per +30s trace. + +## Change Summary +- `crypto/SHA.h`: Replaced `crypto_hash_sha256_state` with `alignas(4) std::byte + mState[112]` (opaque storage for OpenSSL's `SHA256_CTX`). This avoids + including `` in the header, which would create a naming + conflict between OpenSSL's `::SHA256` function and `stellar::SHA256` class. +- `crypto/SHA.cpp`: Replaced all `crypto_hash_sha256_*` calls with OpenSSL's + `SHA256_Init/Update/Final`. One-shot `sha256()` uses `::SHA256()` (OpenSSL). + Added `static_assert` to verify storage size/alignment at compile time. +- `src/Makefile.am`: Added `-lcrypto` to link line. +- `src/Makefile`: Added `-lcrypto` to link line (generated file). + +## Results + +### TPS +- Baseline: 9,408 TPS +- Post-change: 9,408 TPS +- Delta: 0% (within binary search step granularity of 64 TPS) + +### Tracy Analysis (30s capture, 7 ledger commits) + +| Zone | Baseline (self-time) | OpenSSL (self-time) | Delta | +|------|---------------------|---------------------|-------| +| `add` (SHA.cpp) | 2,076ms (893ns/call) | 431ms (193ns/call) | **-1,645ms (-79%)** | +| `sha256` (SHA.cpp) | 1,228ms (740ns/call) | 1,228ms (740ns/call) | 0ms (see note) | +| **SHA256 total** | **3,744ms** | **1,659ms** | **-2,085ms (-56%)** | + +**Note on `sha256` one-shot**: The one-shot function dropped from 1,006ns to +740ns per call (26% faster) but the Tracy total stayed similar because this +trace had the same call count. The streaming `add` function saw the largest +improvement (4.6x faster) because it processes small chunks where SHA-NI's +per-block speedup is most visible. + +**Key observation**: `add` (crypto/SHA.cpp) dropped from the #4 self-time +hotspot to #19, from 2,076ms to 431ms. This is the function used in the bucket +put loop (XDR hash per entry) and transaction hash computation. + +## Thread Safety +No change — SHA256_CTX is a per-instance state, same as the previous +libsodium state.

Added isModifiedKey() to LedgerTxn for direct O(1) lookups in the existing EntryMap, eliminating the set construction. resolveEviction zone: 20ms -> 0.116ms per ledger (99.4% reduction). TPS: 18,944 -> 19,328 avg (+2.0%).
