Hello,<br><br>First of all, thank you for this great software of rsync. If is extremely flexible and powerfull. <br>(my only regret is that i could not find a version for windows dealing properly with charsets in the files' name, might be patched in a future version of cygwin? anyway this is not the subject here <img goomoji="330" style="margin: 0pt 0.2ex; vertical-align: middle;" src="cid:330@goomoji.gmail">).<br>
<br>I would like to know how, in the version 3, is computed the default Block-Size?<br>I found an old post about this saying it was :<br><br><blockquote style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;" class="gmail_quote">
The closest 2^k approximation of N/10 000, and inside the range 700 -> 16 384.<br></blockquote><br>But running a test on version 3, I computed an estimate of<span style=""> the block size for a 1.9Go file:<br></span><br>
<blockquote style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;" class="gmail_quote">N = <span style=""> </span>1 950 368 768<span style=""></span><br><span style=""></span><span style="">Received = 310 851</span><br>
<span style="">AvBlockSigSize ~= 8.09</span> Byte/Block (from some other tests i made)<br></blockquote><blockquote style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;" class="gmail_quote">
<div><b>BlockSize = 310 851 / 8.09 ~= 38 424</b> <br></div></blockquote><div> </div><span style="">So 38 424 is not in the range and is not far from sqrt(N)</span>?<br><br>Could anyone tell me what is the actual implementation in the last release of Rsync?<br>
<br>Best regards,<br><br>Renaud<br>
