However, the routing engine we devised for route collecting + the amount of RAM we had in the collectors were enough and never required us to turn that feature on. Disk-wise, we found out that xz was a great candidate to replace bz2 and gz as the next compressing methodology for route collecting. I don't remember the results to be honest, but that should be easy to reproduce. However, we decided to not compress data in xz because only bgpscanner was able to read xz data - hence anyone that wanted to use other tools such as bgpdump would not have been able to read them.</span></div> <div style="font-family: Arial, Helvetica, sans-serif; font-size: 10pt; color: rgb(0, 0, 0); background-color: rgb(255, 255, 255);" class="elementToProof"> <br style="color: rgb(0, 0, 0); font-family: "Segoe UI", "Segoe UI Web (West European)", "Segoe UI", -apple-system, BlinkMacSystemFont, Roboto, "Helvetica Neue", sans-serif; font-size: 14.6667px; background-color: rgb(255, 255, 255);" class="ContentPasted1"> </div> <div style="font-family: Arial, Helvetica, sans-serif; font-size: 10pt; color: rgb(0, 0, 0); background-color: rgb(255, 255, 255);" class="elementToProof"> <span style="color: rgb(0, 0, 0); font-family: "Segoe UI", "Segoe UI Web (West European)", "Segoe UI", -apple-system, BlinkMacSystemFont, Roboto, "Helvetica Neue", sans-serif; font-size: 10pt; background-color: rgb(255, 255, 255); display: inline !important;" class="ContentPasted1">>> o You mention the withdraw storm between your peer and their</span><br style="color: rgb(0, 0, 0); font-family: "Segoe UI", "Segoe UI Web (West European)", "Segoe UI", -apple-system, BlinkMacSystemFont, Roboto, "Helvetica Neue", sans-serif; font-size: 14.6667px; background-color: rgb(255, 255, 255);" class="ContentPasted1"> </div> <div style="font-family: Arial, Helvetica, sans-serif; font-size: 10pt; color: rgb(0, 0, 0); background-color: rgb(255, 255, 255);" class="elementToProof"> <span style="color: rgb(0, 0, 0); font-family: "Segoe UI", "Segoe UI Web (West European)", "Segoe UI", -apple-system, BlinkMacSystemFont, Roboto, "Helvetica Neue", sans-serif; font-size: 10pt; background-color: rgb(255, 255, 255); display: inline !important;" class="ContentPasted1"><span style="color: rgb(0, 0, 0); background-color: rgb(255, 255, 255); display: inline !important;" class="ContentPasted13">>></span> peer (and later an announcment storm, I presume).
