mod_servlet and Java Servlets Performance comparison - novalexei/mod_servlet GitHub Wiki
mod_servlet vs Java Servlets
This is not a formal performance comparison. I don't have time and hardware for it. I just ran Apache bench to measure the performance of simple servlet which doesn't really do anything except generating html text of about 750 bytes in size. The bench performed on a local machine.
Software
- Apache httpd version 2.4.23 with mod_servlet
vs
- Apache Tomcat version 7.0.40
HTTP results
Here are the results I got via plain http. In the table rps stands for "requests per second"
| Concurrency | Tomcat (rps) | Apache mod_servlet (rps) | Ratio |
|---|---|---|---|
| 1 | 3834 | 4708 | 1.23 |
| 5 | 15209 | 16095 | 1.06 |
| 10 | 15321 | 18302 | 1.19 |
| 30 | 15794 | 19925 | 1.26 |
| 50 | 15532 | 20077 | 1.29 |
From 6% to 29% performance improvement. Not so bad for the application which essentially doesn't do anything. The measurements for the same servlets via SSL revealed much greater performance difference.
HTTPS results
The results for https are very important because dynamicly generated content very often served via secure channels.
| Concurrency | Tomcat (rps) | Apache mod_servlet (rps) | Ratio |
|---|---|---|---|
| 1 | 11.99 | 69.65 | 5.81 |
| 5 | 43.26 | 163.74 | 3.79 |
| 10 | 54.12 | 171.39 | 3.17 |
| 30 | 49.35 | 166.17 | 3.37 |
| 50 | 45.34 | 162.36 | 3.58 |
From 337% to 580% performance improvement!
Comparison on throughput or average response time has very similar results.
