Scrapebox link checker really slow!

Anyone know why this is happening?

I'm running a list of about 200k posted comments with the link checker and it's really slow. It used to be much faster than the fast poster but now it's horrible. It's been running for 2 days now and I'm about 2/3 trough the list.

my VPS is very fast.. I can still do pretty much anything while the link checker run. It's running windows server 8 and have 2 gig of ram.

Anyone had troubles like this?

Ditch the SB link checker. Use Xrumer's link database analysis. Put it on 300 threads (the most stable number IME) and watch it fly.

Raise the number of threads for the Link Checker in Settings, or maybe the pages are timing out so Scrapebox is using the maximum amount of time on each one.
