After 2 days of importing, importer has imported 45% of posts and topics and it seems that the longer it runs, the slower it gets. At the beginning, 0.01% was taking about minute or so to be imported.
Right now, when i'm at 45%, 0.01% takes about...an hour. Yes, an hour (even after restarting the importer and restarting the whole VM. That's a horrible thing, it let's me think it would take weeks to import that forum.
I've just started a local virtual machine (virtualbox) which is stronger than my web server, hopefully import will be faster. But, so far, it seems that the speed is more or less the same.
Is there ANYTHING i can do to make that process faster? Some code changes in importer, params passed, moving to mruby or anything like that? I would really appreciate any help and ideas.
ps. another horrible thing is that even restarting importer takes a huge amount of time. Running importer again and waiting for skipped 1000's takes about 2 hours each time.
