* also be too low if you use big tiles and a high number<br><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"><div><div class="h5">

</div></div>Well I use small tiles (max-nodes 900.000 on Turkey) plus only 4<br>
threads. (I could use 8 due to Hyperthreading, but kept it at 4). I even<br>
have this problem on single tiles where the osm.gz is like 10MB. There<br>
shouldn&#39;t be a slow down due to memory in that case, should there? (I<br>
cannot check for memory use, as my user rights are too low).<br>
