Hi Michel,
Let me explain my problem in detail.
I am have having one oracle 9i primary database and configuration as below:

LOG_ARCHIVE_DEST_1='LOCATION=/arch/ MANDATORY REOPEN=30'
LOG_ARCHIVE_DEST_2='SERVICE=standby arch optional REOPEN=30'
LOG_ARCHIVE_DEST_STATE_2=ENABLE
LOG_ARCHIVE_DEST_STATE_1=ENABLE
REMOTE_ARCHIVE_ENABLE=TRUE

There are 3 log group with 10M size/member
There are 5 active archive_processses
Database protection mode is in maximum performance mode

Redo change rate is 1.5 MB/s during peak hour and 400KB during normal hour
Network bandwidth between primary and standby database is 2Mbps.

There is no problem in log switch during normal hour but during peak hour redo log switch hangs in primary database because of which no activity can be done.
As i am new to oracle standby database and known that there will be no impact while using maximum performance mode.
What is the reason behind this?
I don't want to increas redo log size and solve the problem as i donot want to loss more data.

Please help me out understand the problem.

Regards
Santosh

Are you sure the problem comes from the standby database?
Disable the second destination, what happens?
