| |
Hi people,
This is 2.4.21-pre4aa3, but the same applies to 2.4.20-vanilla, and i think to any 2.4.x. The NIC is RTL-8139(8139too). I would really like to know what could be done in this situation. The machine (p3-1GHz) is almost unrespobsible. Yes, there are really network card interrupts. So, here it goes. # readprofile -m /boot/System.map | sort -nr +2 | head -20 2600 handle_IRQ_event 23.2143 268 system_call 4.7857 184 fget 3.8333 123 sock_poll 2.5625 421 kfree 2.1927 101 __free_pages 2.1042 288 do_softirq 2.0000 326 skb_copy_and_csum_dev 1.8523 56 restore_fpu 1.7500 232 send_sig_info 1.6111 123 poll_freewait 1.5375 174 __wake_up 1.3594 695 do_schedule 1.2776 19 sockfs_delete_dentry 1.1875 70 del_timer 1.0938 592 save_i387 1.0278 17 ret_from_sys_call 1.0000 111 skb_release_data 0.9911 58 __generic_copy_to_user 0.9062 115 do_pollfd 0.8984
