Looking for 2X4U colocation. Need to maintain a balance between overseas and US users. 60% users are overseas in India and 40% in US and Europe.
What effects geographic location of colo has on performance or access speed of the application? Is downloading a test file the best test for performance of a colo? Can that be misleading? What other tests should be considered before making a decision on colo choice?
a certain host I've been with for over 6 months now experiences what I would consider always very high server load. The server load is normally around 4-6ish, rarely below that. A few times a day it spikes to around 12ish, sometimes even more. The server has 4 cpus. Is this just some really big time overselling? They had downtime once for 2 days when a server crashed, and after that the server load has been really high, when before that it was normally around 1-2, and in the 0.50s
can a Xen disk image be converted to a diskpartition?
Someone is asking whether I can host his disk image at his current host, which he is leaving for poor I/O (wonder why that would be ). I can host a diskimage, but I don't like diskimages (slow, and 100GB isn't very 'comfortable' either). Is there any way out there to convert a disk image into a normal partition?
I use apache with CentOS VPS hosting for my blog. I only host one blog in this VPS account. I have 1.5GB RAM and I have 7, 500 page preview per day. My page loading time is 2-3 seconds (according to the pingdom tool).
I want to know what is the best performance (faster web page loading) W3 Total cache option for VPS hosting blog. Currently I use Disk to enhance for page cache and database cache for disk.
I got 5 wordpress and 5 statics website on this server and 100 visitors by 24H00 each day.
Question 1 : Why the memory is so low and the swap so high ? Question 2 : Why i don't find high usage process in top command ? Question 3 How can i resolve this problem ?
I have a site that is eating up my server resources and need to know what the best solution for this is. I'm thinking of getting another server just for mysql but do not know what specs the server should be to handle the current traffic/database load and have the site run smoothly without slowing down to a snail's pace.
An alternative is to get another server just for the videos being served and leave the database and html on the current server. This is where I'm stuck and don't know what route to take with this.
I've attached screenshots of top and bandwidth usage per day. Hopefully with this information you could tell me if I need another server or if there are any things I can do to the current server to help things move faster.
I am running in a High load problem lately. I have one of those cheap 1and1 servers which was running fine until 2 weeks ago. Once I rebooted accidentaly, it did not come back with some unrepairable kernel errors and I had to re-image it.
I chose to reimage the server with CentOS 5, for better support. The new re-image worked fine for some days, at least so I thought and now I am having high loads. The server crashes if not monitored every moment as the load is unpredictable.
Just a restart of the Apache will bring the server back to normality, but I am not sure if it is apache or some other script to be blamed. I have beeing monitoring through apache server-status, but I cannot organize something unusual in the high load moments.

So my server is "unresponsive" for abour 18 hours, burst net didnt answer my tickets and I dont know what to do. Ive been with this setup for almost 5 months with no problems, No changes have been made to hardware or software.
I've got a server in a local colo facility. both the facility and my server are slowly falling apart. Rather than investing in hardware and then shipping it to some location and hoping it doesn't break, I've decided to investigate VPS.
What I am finding is puzzling me. Why do providers charge so much for disk space? My current old p3-733 has a 30gb drive, I could deal with about 15gb but with some 'flex' room (i.e. a virtual drive for uncompressing files or some such). It's a personal server for me and a couple of friends, it doesn't get much traffic, I don't need a heck of a lot of bandwidth, nor anything flashy, just Ubuntu 8.04. I see places offering plenty of traffic for a decent price, yet little in the way of storage. I just don't get it.
A year ago I was here wanting to trade my class C for a dedicated server. I realize now that it would be pretty difficult for providers to do this, because if I wanted to yank my class c they'd have to renumber. But if anyone is still interested, let me know.
I've decided I want cPanel installed on my iWeb dedicated box. They informed me it will require a reinstall. Before they do this I wanted to image the disk and download the image to my PC. Is this possible to do via SSH? I'd prefer an open-source free solution.
I have a site with a lot of data (almost 20-30gigs). I want to pkgacct the site to transfer to another server but the harddisk gets full and the pkgacct stops working.
Which files and folders can I delete on the server without touching critical CPanel files? I want to delete as many as folders so that I can have enough space for the packaging process.

I get write errors when i use sysinstall. As for the raid status. Its fine.
One of the things people seem to bring up a lot is disk IO Performance.
Why? Because theres little you can do about a customer being stupid and creating a disk swap nightmare.
There is however something you can do to reduce the impact across your clients, Have a separate raid array for swap space.
This does 2 things, it splits some of the Disk IO across 2 arrays, but more important it reduces the affect someone overusing there swap will have on the ones that are not.
