5 Tips to Boost the Performance of Your Apache Web Server

by Gabriel Cánepa

According to a recent report by Netcraft (a well-known Internet company that provides among other services web browser usage statistics), Apache continues to be the most widely used web server among sites and Internet-facing computers.

Additionally, Apache keeps experiencing the largest growth among the top web servers, followed by Nginx andIIS. Thus, if you are a system administrator in charge of managing Apache installations, you need to know how to make sure your web server performs at the best of its capacity according to your (or you client’s) needs.

In this article we will discuss a few tips that will help you ensure that Apache will run smoothly and be able to handle the number of requests you are expecting from remote clients.

However, please keep in mind that Apache was not designed with the objective of setting benchmark records – but, even so, it is still capable of providing high performance in almost any usage case you can possibly think of.

​TIP #1: Always keep Apache updated to its latest version

TIP #2: If you are using a Kernel older than 2.4, consider upgrading now

TIP #3: Choose the Multi-Processing Module (MPM) that works best for your case

TIP #4: Allocate RAM wisely for Apache

TIP #5: Know your applications

Web server performance comparison

by DreamHost.com

Over the years, a myriad of web servers have been written.

Apache, being one of the oldest, is the most widely used today. However, it was implemented with a scaling mechanism that can be relatively inefficient in some ways. Some newer web servers have come out in the last few years that attempt to address some of the shortcomings of Apache. The most prominent of these are Lighttpd and Nginx.

This article examines the relative performance of each web server to see how they compare head-to-head. Keep in mind that this is not meant to be an exhaustive be-all end-all performance comparison. The hope is to simply give a relative performance comparison under common conditions.

Testing method

  • The method to test these web servers uses ApacheBench (an HTTP server benchmarking tool).

  • In each test, 25,000 requests are made for a 5k PNG file locally from a VPS to remove potentially variable network conditions from the equation.

  • Before each test the web server in question was restarted to clear out any potential caching or other issues that may interfere with results.

  • Each test was run with different numbers of concurrent requests to gauge performance at different levels of usage. (Consider that it’s very common for browsers to allow up to 6 concurrent connections per single user you have browsing a site. Therefore 10 users browsing your site at the same time would amount to approximately 60 concurrent connections).

The New Way

If you’re looking for a very modern way to check and monitor performance, you should give Performance Analyzer a try.

Use Case - Tamper-resistant Clinical Trials


Blockchain PoCs were unsuccessful due to complexity and lack of developers.

Still the goal of data immutability as well as client verification is a crucial. Furthermore, the system needs to be easy to use and operate (allowing backup, maintenance windows aso.).


immudb is running in different datacenters across the globe. All clinical trial information is stored in immudb either as transactions or the pdf documents as a whole.

Having that single source of truth with versioned, timestamped, and cryptographically verifiable records, enables a whole new way of transparency and trust.

Use Case - Finance


Store the source data, the decision and the rule base for financial support from governments timestamped, verifiable.

A very important functionality is the ability to compare the historic decision (based on the past rulebase) with the rulebase at a different date. Fully cryptographic verifiable Time Travel queries are required to be able to achieve that comparison.


While the source data, rulebase and the documented decision are stored in verifiable Blobs in immudb, the transaction is stored using the relational layer of immudb.

That allows the use of immudb’s time travel capabilities to retrieve verified historic data and recalculate with the most recent rulebase.

Use Case - eCommerce and NFT marketplace


No matter if it’s an eCommerce platform or NFT marketplace, the goals are similar:

  • High amount of transactions (potentially millions a second)
  • Ability to read and write multiple records within one transaction
  • prevent overwrite or updates on transactions
  • comply with regulations (PCI, GDPR, …)


immudb is typically scaled out using Hyperscaler (i. e. AWS, Google Cloud, Microsoft Azure) distributed across the Globe. Auditors are also distributed to track the verification proof over time. Additionally, the shop or marketplace applications store immudb cryptographic state information. That high level of integrity and tamper-evidence while maintaining a very high transaction speed is key for companies to chose immudb.

Use Case - IoT Sensor Data


IoT sensor data received by devices collecting environment data needs to be stored locally in a cryptographically verifiable manner until the data is transferred to a central datacenter. The data integrity needs to be verifiable at any given point in time and while in transit.


immudb runs embedded on the IoT device itself and is consistently audited by external probes. The data transfer to audit is minimal and works even with minimum bandwidth and unreliable connections.

Whenever the IoT devices are connected to a high bandwidth, the data transfer happens to a data center (large immudb deployment) and the source and destination date integrity is fully verified.

Use Case - DevOps Evidence


CI/CD and application build logs need to be stored auditable and tamper-evident.
A very high Performance is required as the system should not slow down any build process.
Scalability is key as billions of artifacts are expected within the next years.
Next to a possibility of integrity validation, data needs to be retrievable by pipeline job id or digital asset checksum.


As part of the CI/CD audit functionality, data is stored within immudb using the Key/Value functionality. Key is either the CI/CD job id (i. e. Jenkins or GitLab) or the checksum of the resulting build or container image.
