Hi list, I have 2 servers 1 running redhat 7.2 and the other running suse 7.3. the hardware config is :
RH7.2: Fast desktop (IDE HDD/128 MB memory PIII 550 MHz). Suse 7.3: Low end server (Ultra SCSI 2, PIII 850 MHz, 256 MB RAM). Now i expect to see the suse server go faster than RH, but i am having the reverse happening. The RH server returns a query about 5 times faster. For eg: on RH: ---------------------------------------------------------------------------- mysql> select straight_join docm.document_id, docm.document_title, docm.document_date, sources.source_name, cliptypes.cliptype, byline.byline from keywords, documents_7 as docm use index (PRIMARY), dockeys_7 as dock, sources, cliptypes, byline where keywords.keyword_id=dock.keyword_id and docm.document_id=dock.document_id and docm.document_source_id = sources.source_id and docm.document_cliptype_id = cliptypes.cliptype_id and docm.document_byline_id = byline.byline_id and ( keywords.keyword="assam" ) order by docm.document_id; <Lots of results> | 219401 | WRONG POLICIES ARE THE BANE OF ASSAM | 2000-08-21 | THE HINDUSTAN TIMES (DELHI) | N. A. | PARASHAR, UTPAL | +-------------+--------------------------------------------------------------+---------------+------------------------------------------------+----------+------------------------+ 276 rows in set (2.78 sec) same query on suse: <Lots of results> | 219401 | WRONG POLICIES ARE THE BANE OF ASSAM | 2000-08-21 | THE HINDUSTAN TIMES (DELHI) | N. A. | PARASHAR, UTPAL | +-------------+--------------------------------------------------------------+---------------+------------------------------------------------+----------+------------------------+ 276 rows in set (7.06 sec) This happens for all queries. Of course the data is the same on both systems. The mysqld is what comes with the distrib. (RH - mysql-3.23.22-6 / Suse - mysql-3.23.41-17). I did try to use the official binaries from mysql.com but, i get the same results on both systems. I will probably install Redhat on the suse system, but can anyone think of why this happens and what can i do to improve the response. As of now the rowcount for the largest table is 221165. Has anyone else noticed similar results?
