How can I increase parallel count and Max queue size?
This article applies to all MetaDefender Core V5 releases deployed on Windows systems.
The only reason to increase the scaling up performance is if you have 32-48 CPU cores and require your file to be processed very fast.
In order to increase the scaling up performance, there are two common approaches, as follows:
Approach A
When the MetaDefender Core queue is full of incoming scan requests, they will be denied until there is a free slot. To change the queue size, you can use the following API call:
PUT /admin/config/scanWith the following body:
{ "max_queue_per_agent": 500}Postman:
Note that you will need the API key from the MetaDefender Core deployment to perform this call.

Approach B
Another way to better utilize your CPU is to increase the parallel number of scans running per engine.
This way you can tell the Core how many scans should run simultaneously per engine. This applies to engines supporting multi-threaded scan.
To change this, you have to use the parallelcount setting key, explore the details at MetaDefender Configuration.
Once you have configured the parallel scan count, be sure to restart the MetaDefender Core service for the changes to take effect.
