Debian - error while loading shared libraries The apt-get error is because your system is low on memory. What does ldd doctotext return? |

High load average due to high system cpu load (%sys) Your current system apparently has hyperthreading enabled while the old one hadn't. That may be the culprit; HT performance can be tricky sometimes. I'd try turning HT off (in the BIOS) and see if it makes a significant difference. |

High load average due to high system cpu load (%sys) Well these normally work pretty well under linux... are you sure you're not under some DDoS attack? |

High load average due to high system cpu load (%sys) From the interface name I suppose this is a Dell system with e1000 or e1000e built-in interfaces? |

High load average due to high system cpu load (%sys) What kind of network interfaces are you using? What does "ethtool -k <iface>" reports? |

What are the differences between channel bonding modes in Linux? That's true, however most switches don't allow static link aggregation configuration and call aggregates "LACP mode". |

Can't access to a iSCSI volume Well, "file" has the advantage of working for about anything, block devices, media files, etc :) |

Can't access to a iSCSI volume @jmiguel.rodriguez, this is definitely strange. What are you exporting from the iSCSI target? is it a fileIO or a blockIO device? You should give more details on the target type (lio, iet, tgt; etc) and configuration. |

file read performance degrades as number of files increases run "iostat -mx 2" while running your test, and see how many IOs there are, and the usage percentage of the device while reading, and please post an example of output. |

Good NFS configuration for Small Network (NFS Performance Issues) added 66 characters in body |

Good NFS configuration for Small Network (NFS Performance Issues) UDP doesn't insure correct data transmission. TCP does, at some cost (mainly CPU). A few years ago, most computers weren't fast enough to saturate a GigE interface using TCP/IP, but that's not a problem anymore. Furthermore if your network is heavily loaded, or your NIC very busy, UDP traffic may lose lots of packets thus achieving low performance overall. See ifconfig and nfsstats output for information. |
