Re: Slow query execution over high latency network

Hi Andrej,

Thanks a lot for taking a loot at the tcpdump data.

Pretty sure, yes. I get the same performance when executing the
hibernate-generated query using JDBC,
even setting a large fetch-size doesn't improve the situation:

Could it be jdbc driver struggles with the huge number of columns (~500)?

Thanks, Clemens
