Slow queries from time to time

Support Bug
1

Hi all, we observed that stardog takes longer to reply to the same query from time to time.

We are using a simple query as show below. There is not extra queries or load in the server.

We run the query below 100 times. The average time is 2s but sometimes takes one query 11s to reply.

select ?s where {?s a owl:Class} order by ?s

How can we monitor all queries currently running at stardog?

You can use the stardog-admin query list command to list all of the running queries at any given time, and then stardog-admin query status <id> to get details of any individual one.
