No. _Now_ it is about 1500-2000 req/sec with 10-20% CPU utilization. Number of 'Total transferred' and 'HTML transferred' does not equal to 80000 multiplied by size of the page. That are strange tests actually - I managed to get 9000 requests per second from epoll server (only once!) and 8900 from kevent (two times only), sometimes they both drop down to 2300-2700 req/s. > Ingo -- Evgeniy Polyakov - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||
