What's the kernel version you're using? Is it 2.4.19? If not, upgrade it. If fact, you may want to upgrade to Red Hat Linux 8.0 due to Ext3 support that wasn't available until Red Hat Linux 7.2. Ext3 mounted with data=journal can offer significant performance increases for servers with frequent I/O reads/writes over Ext2. Is this a router? If so, make sure to check the "Optimize as router" box in the kernel configuration. ip_frag_low_thresh and ip_frag_high_thresh should be increased in some situations. This will allow your server to take far more connections and put them together in memory before having to ditch their fragments. You can safely increase these to several megabytes without any problems. I'm sorry, but I can't answer your questions. - 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/
