Hi,
There could be any number of reasons for this.
Can I suggest that you look for some MYSQL tuning guides as without a much greater knowledge of your exact database config and structure we cannot help with this.
Tuning is really down to the database adminstrator and the specific database and usage thereof and not specifically a WAMPServer issue.
