1. A method of operation for a network traffic system comprising:

  • gathering a first portion of network traffic from a first network port, the first portion based on a first network filter executing on a first core of a multicore processor, the first portion including state parameters of the network traffic, the first portion stored to a first capture file having a block size of greater than or equal to 1 megabyte (MB);

    compressing the first capture file using a second core of the multicore processor while concurrently storing a second portion of the network traffic in a second capture file, the second portion gathered from a second network port and based on a second network filter;

    gathering a third portion of the network traffic from a third network port, the third portion based on a third network filter;

    replaying time-shifted network traffic from the gathered network traffic in the first capture file, the second capture file, and a third capture file in parallel from the first network port, the second network port, and the third network port respectively;

    concurrent with the replaying, gathering a targeted portion of the time-shifted network traffic from the first network port, the second network port, and the third network port, the targeted portion based on a target network filter executing on a selected core of the multicore processor, the selected core identified by a predefined core affinity value, the targeted portion stored to a target capture file having a block size great than or equal to one megabyte (MB); and

    searching the target capture file using a search value to obtain search results for displaying on a display device.
