sql-bench/Comments/FrontBase.benchmark

+# This file describes how to run benchmarks and crash-me with FrontBase
+
+Installed components:
+
+- FrontBase-2.1-8.rpm
+  (had to run with rpm -i --nodeps; the rpm wanted libreadline.so.4.0,
+   but only libreadline.so.4.1 was available)
+
+- DBD-FB-0.03.tar.gz
+  (perl Makefile.Pl;
+   make;
+   make test;
+   make install;)
+
+- DBI-1.14.tar.gz
+  (perl Makefile.Pl;
+   make;
+   make test;
+   make install;)
+
+- Msql-Mysql-modules-1.2215.tar.gz
+  (perl Makefile.Pl;
+   make;
+   make test;
+   make install;)
+
+After installations:
+
+- cd /etc/rc.d
+  FBWeb start  
+  FrontBase start
+
+- cd /usr/local/mysql/sql-bench
+- FBExec &
+- FrontBase test
+
+crash-me:
+
+There were a lot of troubles running the crash-me; FrontBase core
+dumped several tens of times while crash-me was trying to determine
+the maximum values in different areas.
+
+The crash-me program itself was also needed to be tuned quite a lot
+for FB. There were also some bugs/lacking features in the crash-me
+program, which are now fixed to the new version.
+
+After we finally got the limits, we runned the benchmarks.
+
+benchmarks:
+
+Problems again. Frontbase core dumped with every part of the
+benchmark (8/8) tests. After a lot of fine-tuning we got the
+benchmarks to run through. The maximum values had to be dropped
+down a lot in many of the tests.
+
+The benchmarks were run with the following command:
+
+perl run-all-tests --server=frontbase --host=prima
+--cmp=frontbase,mysql --tcpip --log
