Hello,
My name is Tom Whiting, and I've been working with linux servers for the past 20 or so years.
Looking at your issue, the best response is to see what's causing the high server load, at which time the rest of things will fall into line, most definitely.
I can start looking into this this weekend for you (today, if you like), and should have a reasonable fix by Monday. i did post 7 days, mainly because that's the length of time it COULD take to resolve the issue, find it, etc. However, in most cases, 2-3 days tops.
If you'll look at my profile, you'll see numerous 5* ratings, and projects like this that have been done in the past. While my bid may not be the cheapest, it's certainly cheap for the skillset I bring to the table, as you can see by looking at my profile.
If you have any questions or concerns, please, don't hesitate to contact me.
I look forward to working with you on this project.
Tom Whiting
