[basex-talk] multi-threaded XQueries

Hi All,

I created one database of 1GB in size, and have a batch of *read-only*queries to be performed. Each query is quite simple, so there is not much room to improve. All the queries are executed through *XQJ api.*

If these queries are sequentially executed, it costs 5~8 seconds per query.

To speed it up, I tried to executed it in a multi-thread way. But turns out to be much slower than the sequential one.

This is what I wrote for each thread:

public void run() { try { XQConnection conn = ds.getConnection(); XQSequence rs = conn.prepareExpression(input) .executeQuery(); //process the query result conn.close(); } } catch (Throwable e) { e.printStackTrace(); } }

Anyone has the idea on how to improve the batch of queries.

Thanks,
