<div dir="ltr">Hi,<div><br></div><div>We're currently testing the migration from MySQL towards PostgreSQL.</div><div><br></div><div>Serializing the data went pretty much as expected, took about 30 minutes to complete.</div><div>After that we went ahead and prepared a PostgreSQL database for this test and created the schemas/acls.<br></div><div>From there we\ve started the rt-importer tool.</div><div><br></div><div>Now with the importer we've noticed it takes a very long time to finish. Exporting took about 30 minutes (maybe even less if we give the VM more resources) but importing takes about 6 hours.....</div><div><br></div><div>From monitoring the resources we;ve noticed that the importer only uses 30% CPU of 1 core (4 cores available) and only 20% memory (4GB available). Compared to the serializer this is nearly nothing (serialzizer uses allot more CPU and nearly all memory).</div><div><br></div><div>Also, the postgres server is nearly idle. Only one process using 20% CPU of 1 core (16 available) and nearly no memory (64GB available). On top of that, the disk IO is nearly nothing. So basically the DB server doesn't do a thing (or so it seems).</div><div><br></div><div>Are there ways to speed up the rt-importer process???</div><div><div><br></div>-- <br><div class="gmail_signature">Bart G.</div>
