请大神帮忙看看informix数据库的参数该如何优化!

gcllk

数据库的版本是IBM Informix Dynamic Server Version 9.40.FC3，需要单机跑在HP-RX6600安腾服务器上，服务器的配置如下:4个1.4GHz的双核CPU，32GB内存，我把我的onconfig参数贴到下面，请各位大神看看有没有需要优化的地方，谢了!

补充:用来作为单位OA的后台数据库，OA系统B/S结构，忙时并发用户200-300

# can be set to smaller values.
#
# If dynamic logging is off, LTXHWM/LTXEHWM need to be set to smaller values
# to avoid long transaction rollback hanging the server due to lack of logical
# log space, i.e. 50/60 or lower.
