mysql ist langsam mit InnoDB beim einfügen im Vergleich zu MYISAM

Ich gerade installiert, MySQL 5.5, die Standard-engine InnoDB und realisiert INSERT-Abfragen sehr langsam! Nach der Deaktivierung der general-log-es wurde ein bisschen besser, aber immer noch sehr langsam. Ich die Analyse von mysql das problem zu finden, aber keine chance.

Hier ein benchmark Vergleich:

Prüfung eine(n) MYISAM-Tabelle mit 500 Zeilen.
- 5866 inserts pro Sekunde.
- 128866 Zeile Lesevorgänge pro Sekunde.
- 56306 updates pro Sekunde.

Prüfung eine(n) INNODB-Tabelle mit 500 Zeilen.
- 9-inserts pro Sekunde.
- 28539 Zeile Lesevorgänge pro Sekunde.
- 4358-updates pro Sekunde.

Habe ich 9 einfügen von Abfragen auf InnoDB gegenüber 5866 mit MyISAM.

#*** INNODB Specific options ***

# Additional memory pool that is used by InnoDB to store metadata
# information.  If InnoDB requires more memory for this purpose it will
# start to allocate it from the OS.  As this is fast enough on most
# recent operating systems, you normally do not need to change this
# value. SHOW INNODB STATUS will display the current amount used.
innodb_additional_mem_pool_size=64M

# If set to 1, InnoDB will flush (fsync) the transaction logs to the
# disk at each commit, which offers full ACID behavior. If you are
# willing to compromise this safety, and you are running small
# transactions, you may set this to 0 or 2 to reduce disk I/O to the
# logs. Value 0 means that the log is only written to the log file and
# the log file flushed to disk approximately once per second. Value 2
# means the log is written to the log file at each commit, but the log
# file is only flushed to disk approximately once per second.
innodb_flush_log_at_trx_commit=1

# The size of the buffer InnoDB uses for buffering log data. As soon as
# it is full, InnoDB will have to flush it to disk. As it is flushed
# once per second anyway, it does not make sense to have it very large
# (even with long transactions).
innodb_log_buffer_size=8M

# InnoDB, unlike MyISAM, uses a buffer pool to cache both indexes and
# row data. The bigger you set this the less disk I/O is needed to
# access data in tables. On a dedicated database server you may set this
# parameter up to 80% of the machine physical memory size. Do not set it
# too large, though, because competition of the physical memory may
# cause paging in the operating system.  Note that on 32bit systems you
# might be limited to 2-3.5G of user level memory per process, so do not
# set it too high.
innodb_buffer_pool_size=512M

# Size of each log file in a log group. You should set the combined size
# of log files to about 25%-100% of your buffer pool size to avoid
# unneeded buffer pool flush activity on log file overwrite. However,
# note that a larger logfile size will increase the time needed for the
# recovery process.
innodb_log_file_size=49M

# Number of threads allowed inside the InnoDB kernel. The optimal value
# depends highly on the application, hardware as well as the OS
# scheduler properties. A too high value may lead to thread thrashing.
