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 the same server
Server parameters:
- Operating system: Windows Server 2019 Datacenter
- CPU: 3.00 GHz, 64 bit, 16 processor (XEON Platinum 8124M)
- RAM: 32 GB
- Hard disk: 100 GB
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:
- Core queue size: 100
- CDR parallel count (
parallelcount_ds): 5 - Email Gateway Security concurrency threshold (
concurrency_threshold): 1
