yeah it should be running ok now.
It really depends on the traffic we are getting and the type of traffic also.
i.e. from time to time we get malicious traffic on the site, and they essentially send a large amount of hits our way and basically kill all processes.
Sometimes some processes get stuck and that slows other things down.
I am still tuning the performance. I have also noticed when i am connected via FTP it tends to slow the rest of the site down which is interesting
Over all it is far better than it used to be 🙂
