+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,

-# 📈 Gazan Prometheus Metrics Reference
-
-This document outlines Prometheus metrics for the [Gazan](https://github.com/sadoyan/gazan) reverse proxy.
-These metrics can be used for monitoring, alerting and performance analysis.
-
-Exposed to `http://config_address/metrics`
-
-By default `http://127.0.0.1:3000/metrics`
-
----
-
-## 🛠️ Prometheus Metrics
-
-### 1. `gazan_requests_total`
-
-- **Type**: `Counter`
-- **Purpose**: Total amount requests served by Gazan.
-
-**PromQL example:**
-
-```promql
-rate(gazan_requests_total[5m])
-```
-
----
-
-### 2. `gazan_errors_total`
-
-- **Type**: `Counter`
-- **Purpose**: Count of requests that resulted in an error.
-
-**PromQL example:**
-
-```promql
-rate(gazan_errors_total[5m])
-```
-
----
-
-### 3. `gazan_responses_total{status="200"}`
-
-- **Type**: `CounterVec`
-- **Purpose**: Count of responses by HTTP status code.
-
-**PromQL example:**
-
-```promql
-rate(gazan_responses_total{status=~"5.."}[5m]) > 0
-```
-
-> Useful for alerting on 5xx errors.
-
----
-
-### 4. `gazan_response_latency_seconds`
-
-- **Type**: `Histogram`
-- **Purpose**: Tracks the latency of responses in seconds.
-
-**Example bucket output:**
-
-```prometheus
-gazan_response_latency_seconds_bucket{le="0.01"}  15
-gazan_response_latency_seconds_bucket{le="0.1"}   120
-gazan_response_latency_seconds_bucket{le="0.25"}  245
-gazan_response_latency_seconds_bucket{le="0.5"}   500
-...
-gazan_response_latency_seconds_count  1023
-gazan_response_latency_seconds_sum    42.6
-```
-
-| Metric                  | Meaning                                                       |
-|-------------------------|---------------------------------------------------------------|
-| `bucket{le="0.1"} 120`  | 120 requests were ≤ 100ms                                     |
-| `bucket{le="0.25"} 245` | 245 requests were ≤ 250ms                                     |
-| `count`                 | Total number of observations (i.e., total responses measured) |
-| `sum`                   | Total time of all responses, in seconds                       |
-
-### 🔍 How to interpret:
-
-- `le` means “less than or equal to”.
-- `count` is total amount of observations.
-- `sum` is the total time (in seconds) of all responses.
-
-**PromQL examples:**
-
-🔹 **95th percentile latency**
-
-```promql
-histogram_quantile(0.95, rate(gazan_response_latency_seconds_bucket[5m]))
-
-```
-
-🔹 **Average latency**
-
-```promql
-rate(gazan_response_latency_seconds_sum[5m]) / rate(gazan_response_latency_seconds_count[5m])
-```

-## 🔌 Running the Proxy
+## About binaries
 
-```bash
+**glibc** builds are in general faster, but have few, basic, Glibc dependencies:
-./gazan -c path/to/main.yaml
+
+**musl** builds are 100% portable, static compiled binaries and have zero system dependencies.
+In general musl builds have a little less performance.
+
+The most intensive tests shows 107k-110k requests per second on **Glibc** binaries against 97k-100k **Musl** ones.
+
+For running **Aralez** on very old hardware, CPUs prior Haswell, (launched before 2013) use `aralez-x86_64-compat-*.gz`
+For getting the best performance on newer hardware use `aralez-x86_64-*.gz`.
+

+## Aralez, Nginx, Traefik performance benchmark
+
+This benchmark is done on 4 servers. With CPU Intel(R) Xeon(R) E-2174G CPU @ 3.80GHz, 64 GB RAM.
+
+1. Sever runs Aralez, Traefik, Nginx on different ports. Tuned as much as I could .
+2. 3x Upstreams servers, running Nginx. Replying with dummy json hardcoded in config file for max performance.
+
+All servers are connected to the same switch with 1GB port in datacenter , not a home lab. The results:
+![Aralez](https://raw.githubusercontent.com/sadoyan/aralez/refs/heads/main/assets/bench.png)
+
+The results show requests per second performed by Load balancer. You can see 3 batches with 800 concurrent users.
+
+1. Requests via http1.1 to plain text endpoint.
+2. Requests to via http2 to SSL endpoint.
+3. Mixed workload with plain http1.1 and htt2 SSL.
