最近新装了一台IBM X346服务器 2*3G CPU 2G内存 ，硬盘做的raid0。目前感觉速度很慢，还没有我2*800 CPU 512MB内存的机器快，请大家帮我看看有哪些要改进的阿.
我把buffer改到过 400000，但是online就起不来了，谁能救下我阿

# all dbspaces specified are invalid, various ad hoc queries will create
# temporary files in /tmp instead.
DBSPACETEMP # Default temp dbspaces
# DUMP*:
# The following parameters control the type of diagnostics information which
# is preserved when an unanticipated error condition (assertion failure) occurs
# during Dynamic Server operations.
# For DUMPSHMEM, DUMPGCORE and DUMPCORE 1 means Yes, 0 means No.

# below. Otherwise it behaves as in (0) above.
# 2 => Use costs regardless of the transaction isolation
# mode. Nested loop joins are not necessarily
# preferred. Optimizer bases its decision purely
