Arangob cannot send more than 1000 requests
I am using arangob to test the performance of ArangoDB, but arangob cannot send more than 1000 requests. "Total Operations:" is always 1000.
My output is as follows.
$./arangob --server.endpoint "tcp://127.0.0.1:8529" --delay --requests 50000 --test-case document --complexity 10 --batch-size 0 --concurrency 1

The problem seems to be caused by the option --delay
. Omitting this fixes the problem when trying. Let's see why it delay
causes problems.
update : --delay
requires a boolean as its argument, eg. --delay true
... By omitting an argument, the command line interpreter interprets the next command line argument as the parameter value --delay
. In your case it is --requests
, so the parameter --requests
will be ignored.
Therefore, the command line should read:
./arangob --server.endpoint "tcp://127.0.0.1:8529" --delay true --requests 50000 --test-case document --complexity 10 --batch-size 0 --concurrency 1

The next output is as follows:
