Hello list, I noticed that for most (if not all) of my queries, the first time the query is run (right after i started the virtuoso server), it takes much longer than all subsequent runs. See e.g. my query timings at
https://dl.dropboxusercontent.com/u/32340538/long_first_query.png Using dstat monitoring, I noticed that during these long first query runs, there is a lot of reading from disk. I have some questions concerning this: * What is the phenomenon I'm seeing here? What is happening? Why is this first run so much slower than all subsequent ones? * Can this 'warmup' phenomenon be reduced somehow so that also the first queries run as fast as the subsequent ones? * Is this phenomenon documented somewhere? Is there a place where I can read and learn more about it?
