Shreder Fastlane vs Alchemy Geyser gRPC: Solana Latency Benchmark
A head-to-head benchmark comparing Shreder Fastlane and Alchemy Geyser gRPC for Solana Geyser gRPC delivery in Frankfurt.
In this 10,000-transaction run, Shreder Fastlane delivered the first valid update for 100.0% of matched transactions. Alchemy Frankfurt delivered 0.0% first in this sample, with published latency deltas of p50 19.55 ms, p95 67.17 ms, and p99 102.82 ms.

Run context and methodology
This report summarizes the Alchemy Geyser gRPC run published on the benchmarks hub. Both endpoints were compared with the same monitored workload and the same Frankfurt benchmark environment.

// First delivery
First-detection share and latency deltas
First-detection share answers a direct question: among matched transactions observed by both endpoints, which provider delivered the first valid update to the benchmark client?
| Provider | First-detection share | p50 latency delta | p95 latency delta | p99 latency delta |
|---|---|---|---|---|
| Shreder Fastlane Frankfurt | 100.0% | 0.00 ms | 0.00 ms | 0.00 ms |
| Alchemy Frankfurt | 0.0% | 19.55 ms | 67.17 ms | 102.82 ms |
The 0.00 ms Shreder row is a latency-delta baseline in this comparison table, not literal zero network latency. End-to-end latency still includes transport, stream processing, client receive time, and application handling.
// Reading the result
What the Alchemy run shows
This benchmark is not a generic provider ranking. It is one controlled Frankfurt run that shows how the tested Alchemy Geyser gRPC endpoint and Shreder Fastlane behaved under the same benchmark workload.
Tail deltas matter
Alchemy’s p95 and p99 latency deltas were materially higher in this run, which matters for workloads sensitive to delayed updates.
Your workload can differ
Region, filters, commitment level, endpoint plan, client machine, and timestamping method can change benchmark outcomes.
// Provider comparison
Alchemy Geyser gRPC vs Shreder Fastlane
Both endpoints belong in the Solana Geyser streaming category. The practical comparison is whether your current stream delivers the data you care about early enough for your application.

How to benchmark Alchemy Geyser gRPC against Shreder Fastlane
Use the published run as a starting point, then test from your own infrastructure. Keep the comparison fair by matching environment, stream configuration, and measurement rules.
Keep placement fixed
Run both endpoints from the same machine and region, and use the same benchmark window.
Keep subscriptions identical
Use the same commitment level, account or transaction filters, and timestamping method.
Track more than the winner
Compare first-detection share, p50, p95, p99 deltas, missed updates, duplicate updates, reconnects, stream errors, and correctness.
Shreder Fastlane vs Alchemy Geyser gRPC FAQ
What does the Alchemy benchmark measure?
It compares which endpoint delivered the same matched Solana transaction first to the benchmark client. The page reports first-detection share and p50, p95, and p99 latency deltas for Shreder Fastlane Frankfurt and Alchemy Frankfurt in a 10,000-transaction run.
What was the result against Alchemy Geyser gRPC?
In this published Frankfurt run, Shreder Fastlane delivered 100.0% of matched transactions first, while Alchemy Frankfurt delivered 0.0% first. The published Alchemy latency deltas were p50 19.55 ms, p95 67.17 ms, and p99 102.82 ms.
Does 0.0% first-detection share mean Alchemy missed every transaction?
No. First-detection share measures who arrived first among matched transactions observed by both endpoints. A 0.0% first-detection share means Alchemy did not deliver the first valid update for any matched transaction in this sample.
Is Shreder Fastlane compatible with Yellowstone Geyser gRPC clients?
Yes. Fastlane keeps a Yellowstone-compatible Geyser gRPC interface. Teams using compatible clients generally keep the same client model and change endpoint and token during migration or testing.
Is Shreder Fastlane an Alchemy Geyser gRPC alternative?
Shreder Fastlane can be used by teams evaluating alternatives to Alchemy Geyser gRPC when they need Yellowstone-compatible Solana streaming with lower latency. The best way to compare both providers is to benchmark them from the same machine, region, commitment level, and filters.
How should I compare Alchemy Geyser gRPC and Shreder Fastlane?
Run both endpoints from the same machine, region, commitment level, filters, measurement window, and timestamping method. Compare first-detection share, p50, p95, p99 latency deltas, missed updates, duplicate updates, reconnects, and stream errors.
Should I use this benchmark as a universal result?
No. Treat it as one published Frankfurt run. Production decisions should be based on benchmarks from your region, filters, hardware, commitment level, and application path.
