Performance guidelines

The following information can be used as guidelines before implementing MataDefender Email Gateway Security at an organization.

Since there are many factors that may affect performance, these test results should not be viewed as performance guarantees.

Factors that may affect performance

Among many others, the following can greatly impact Email Gateway Security performance:

  • Package and configuration

    • set of engines (which engines; how many anti-malware engines)
    • configuration (e.g. Deep CDR or Proactive DLP is enabled or not)
  • System environment

    • physical hardware server or virtualized environment (hypervisor)
    • profile (make, model and number of CPU cores, amount of RAM)
    • storage (make, model and volume; if it is HDD, SSD or RAMDisk)
  • Traffic characteristics

    • number of emails; number, size and file type of email attachments

Test results

Performance is measured by the number of processed emails in a certain timeframe interval. In the test scenarios below, the traffic was generated by using real-world attachment number, attachment size and attachment type distributions.

In all cases below:

  • MetaDefender Email Gateway Security was deployed as an SMTP relay

  • CDR was enabled in every case, and was on for all supported file types

  • Email Gateway Security and Core were deployed on different servers

  • Server parameters for Core:

    • Operating system: Windows Server 2019 Datacenter
    • CPU: 3.00 GHz, 64 bit, 8 processors (XEON Platinum 8275CL)
    • Memory: 16 GB RAM
    • Storage: 100 GB Hard Disk
  • Server parameters for Email Gateway Security:

    • Operating system: Windows Server 2019 Datacenter
    • CPU: 3.00 GHz, 64 bit, 16 processors (XEON Platinum 8275CL)
    • Memory: 32 GB RAM
    • Storage: 100 GB Hard Disk
  • Parallel senders:

    • Senders: number of parallel sending threads
    • Delay: delay between emails for each sender
  • Duration for each test execution is 8 hours

  • Product parameters:
