Heu Timo, thanks for your answer. Actually I tried to be careful about empty mailboxes before running the read tests but and my big surprise, I still had empty ones and this might have been the case =/<br><div class="gmail_quote"><div dir="ltr">On Fri, 6 Jul 2018 at 05:44 Timo Sirainen <<a href="mailto:tss@iki.fi">tss@iki.fi</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word;line-break:after-white-space">On 4 Jul 2018, at 20.10, João Paulo Sacchetto Ribeiro Bastos <<a href="mailto:joaopaulosr95@gmail.com" target="_blank">joaopaulosr95@gmail.com</a>> wrote:<br><div><blockquote type="cite"><br class="m_8468634212498468167Apple-interchange-newline"><div><div dir="ltr">Hey guys, <div><br></div><div>Has anybody ever used imaptest to benchmark *ONLY* reads?
