pages load slow during peak hours

dedicated server is AMD 3200+, with 1G memory, vbb forum only, pages load slow during peak hours, but the server load is just less than 2, more than 1.5, the concurrent apache connections (ps -ef|grep apache|wc -l) are round 70, sql connections (ps -ef|grep mysql|wc -l) are about 120,

top output:
23:26:09 up 19 days, 23:42, 1 user, load average: 1.48, 1.65, 1.64

Swap: 2096440k av, 1105688k used, 990752k free 337324k cached

the apache settings:
KeepAlive = Off
MaxKeepAliveRequests = 0
KeepAliveTimeout = 5
MinSpareServers = 10
MaxSpareServers = 20
StartServers = 10
MaxClients = 250

is there anything I can do for better performance? Thanks.
