<p class="MsoNormal"><span lang="EN-GB">I discovered a Heritrix mailinglist(*). Amongst some interesting tips on making the crawl faster, I also read some speed figures far from what we ever get. So I ask you: what do you get as speed values?<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-GB">(I realize that this besides NAS/Heritrix configuration depends much on hardware, memory, disk I/O, network capacity etc. but don’t know which such figures that are most relevant to add to this comparison. Suggestions?)<o:p></o:p></span></p>
