Currently I need to load some logfiles contained in tar (archive) files. To load them into filebeat, I am using gzcat tool to echo the log files inside the archive files using stdin input for filebeat. For a 200mb log file, it takes more than 1 hour. We wonder if there would be any way to speed things up. I was playing with different buffer size and poolsize options but it did not help much. Also, I tried using an SSD drive instead of a regular hard drive but it did not help much either. Any help would be greatly appreciated.
