It's a simple eq, compress time + xfer time( compressed data ) vs xfer time( data ). If you get 50% compression you save 50% of xfer time, so if you bandwidth is 64 kbs, your compressor better be faster than 32 kbs. Most compressors are in the Mbytes/sec range. Anyway, compression is turned off to reduce latency more often than not. Note that lz is extremely fast on the unzip side. _______________________________________________ Devl mailing list Devl at freenetproject.org http://lists.freenetproject.org/mailman/listinfo/devl >From - Mon Apr 30 02:05:39 2001 Return-Path: <devl-admin at freenetproject.org> Received: from hawk.freenetproject.org (postfix@[4.18.42.11]) by funky.danky.com (8.9.3/8.8.7) with ESMTP id SAA04859 for <danello at danky.com>; Sat, 28 Apr 2001 18:15:29 -0400 Received: from hawk.freenetproject.org (localhost [127.0.0.1]) by hawk.freenetproject.org (Postfix) with ESMTP id CA45F5801E; Sat, 28 Apr 2001 15:56:11 -0700 (PDT)
