We observe significant delays in project operations that use firebird
databases. For example, taking a view of a project list sometimes 10 s or more.
We are only three users of this software , so that the load of the server is
very small. We use a CAD system on windows, which saves a few settings in a
Firebird database.
Firebird is running on a server with openSUSE 13.1. The manufacturer has
released only version 2.50 of Firebird , but the problems exist also with
version 2.5.2.
The server has a RAID 5 from three disks, 16GB RAM and an Intel Xeon
E5- 2407 CPU 0@2.20GHz , 4 cores . The *.fdb data resides on a partition that
is partitioned with ext4 under LVM, but the problem exist also if I move them
to a ram-disk. They are 1-10 MB in size - so rather small.
Networking works over a Broadcom BCM95720.

Reproducible: Always

Steps to Reproduce:
Sorry only with the cad-system possible
Actual Results:
slow response > 10 - 40s

Expected Results:
fast response < 2 s
