> Try putting a 1MB pdf file encoded in base64 into the payload Try to use the tab: File https://jmeter.apache.org/usermanual/component_reference.html#HTTP_Request > File Path: Name of the file to send. If left blank, JMeter does not send a file, if filled in, JMeter automatically sends the request as a multipart form request. > When MIME Type **is empty**, JMeter will try to guess the MIME type of the **given file. ** > If it is a POST or PUT or PATCH request and there is a single file **whose 'Parameter name' attribute (below) is omitted**, then the file is sent as the entire body of the request, i.e. no wrappers are added. Fill two columns only: - File path - MIME but don't will the column Parameter name As a result you will send 1 MByte, 10 MBytes, 100 MBytes witout any limits and memory overheads. About memory overheads -- yes, you can put the long content into the JMX file, as a result the file size will be 10 MBytes for example. A file content in memory is a UTF-16 String, it will have a size ~ 40 MByte. Each thread will have a JMX content copy. Xmx1g is a HEAP Size for 1000 / 40 = 25 threads, but 100 threads will try to allocate 4g ram, it will be a root cause of OOM Error The same script without request content, but the file link only, will work well without the OOM Error -- This is an automated message from the Apache Git Service.
