Does it also work (slowly) during the benchmark ?
That simulates your 'long running work'.

What everybody here tries to explain to you is that the problem is most probably in your DB driver (in Smalltalk or further down): it probably cannot do more than one concurrent request (as it is currently implemented). That is not a Seaside nor a fundamental Smalltalk problem.

Try investigating that aspect, separate from Seaside.
