Hi, we have problem with our site - www.audiostereo.pl. Site running not so fast, but acceptable, but adding posts its lottery. Sometimes its 2-5 seconds, sometimes even 10 and more. It was even 30-60 seconds, but Ive changed search engine rules. Now it takes data from only last 3 years. Search index was 4gb+ so that was one of the reasons. After cutting serach it a little bit better now - but still to slow for our users.  We have 2 servers - one with apache for files and 2nd one for db.
