I'm doing my initial tests on IBO Kylix beta and am noticing
significant differences in performance between ibo windows and ibo
kylix. Can anyone enumerate some of the issues that determine the
performance factors on Linux?

I'm running Mandrake 9 on an Intel XEON 2GHZ processor, firebird
running on SUSE 8.x on a Dual Intel XEON 550MHZ.

Using TIBODatabase and TIBOQuery, I run queries against a table that
has almost 1.7 million rows, no binary data, just double, varchar,
timestamp and date timestamp columns. On Windows, some queries that
execute in less than a second will take 30 seconds to a minute on Linux.

I ran into several difficulties compiling the .dpk's in Kylix. In
addition to many case corrections (unit name case not matching source
references), I receive the following error:

[Fatal Error] ibo40vrt.dpk(39): File not found: 'ib_controls.dpu'

when trying to compile/install ibo40vrt.dpk - and other packages as well

Thanks in advance for any assistance.
