I've got a newly designed magento e-commerce site with 5000 products. Initial homepage loads fine.. second page takes very long (20+ seconds) or doesn't load at all. No slow query's in the log. Even loading second page with no database calls takes forever. Dedicated and optimized server (4 other websites work fine on this server). No clear error's in the errorlogs what could cause this.
I need help debugging this problem.
