I have a dual processor server and today I was monitoring CPU usage using the ‘top’ command
There was a mysql process I was tweaking around with where the CPU % kept jumping over 100%.. It went up to 155%, 175%, 180% on numerous occasions.
My question is on a dual processor machine does ‘top’ measure CPU usage between 0% and 200% or does the usages I saw earlier mean my server was getting REALLY overloaded?
If you have experience with large mysql databases please share your thoughts about a new MySQL server. If all other parameters are the same, what is better for a 6-10 GB MySQL db, dedicated server?
Dual XEON or Dual Opteron 2212 Dual Core Processor?
Also, any advice on suggested RAM, partitioning, OS, etc. are welcome. Current MySQL version used is 4.1.21.
I am trying to decide to run my heavy database community site over at a new host but am looking to create a good package customed for high bandwidth.
I can decide from going with ONE Dual Quad-Core 2.0 Processor(4 gigs of ram) or TWO Intel Xeon 3210 2.1 GHz Quad Core Processor servers(4 gigs of ram each) with a Virtual Rack Container.
With having both the lower servers on the virtual rack, will the site manage with the same power as the Dual Quad Core since it is on a rack?
I want to colo dual xeon 3ghz/ 2 x 250 sata drive and Dual core 3.0 / 2 x250 Sata drive.
How much amp these server need? One colo company said 4amp for dual and 2 for dual core. Do I need 6amp for 2 servers? Rack comes with 15amp so I need half rack?
at getting PDUs for the new facility where we plan to move our servers to. Our cabinet will have 2*20a circuits, so we're thinking of getting 2 APC PDUs (1 per circuit). Some offer remote reboot capability.
Our servers (Dell PowerEdge) have dual power supplies, and I assume the best thing is to plug one power supply into each circuit, so things stay up even if a circuit fails.
So, how would this work if we want to reboot? The servers can run on only one power supply, so does that mean we have to click reboot on the web interface of each PDU at exactly the same time?
I've never worked with PDUs before.. just cheap power strips and a call to the datacenter
But say: I have 2 servers, one with a dual CPU and another one with a single CPU but dual core. The CPUs have all the same specification (bus speed, cache, frequency, etc). Which one would perform better for web hosting (php, mysql)?
I'm about to purchase a 2nd server to be used as a database/app server alongside my current server (of which will be the web server).
I wish to use 2 x 146GB 10K SCSI hard disks (in RAID 1) on the database server, but will be keeping 2 x 320GB SATAII 16M in RAID 1 on the web server. Will the SATA hard disks affect the performance / effectiveness of the SCSI disks or will I benefit from SCSI even though they're only in the database server?
Also, I'm going for 10K hard disks over 15K because they $20 per month cheaper and it's already expensive ($150 p/m for the two 10K or $170 p/m for 2 x 15k). Taking into account the already hefty price, is it worth the extra for 15K?
I just added a database server in private network and moved the database for Vbulletin Forum to this server.
But some how, the Forum is loading extremely slow compare to before ( when it was on the localhost). Also, Compare to another website on server (using local database) it is much slower.
One thing good is the load is lower
2 servers are connected via 10mbs private link, both servers are at Softlayer.
I'm running a message board and it looks like I've outgrown the low end xeon 3040 1.86GHz dual core server, and the bulk of the CPU load is going to mysqld. I'm debating between offloading the DB to a dedicated server vs upgrading the existing server and hosting the web server and db on the same machine.
Any thoughts on the better approach? fwiw, the load from apache seems next to nothing right now, but I am also planning on adding an SMTP server for user registrations and general support email.
I'm also not super familiar with dual-core and dual processor machines. Does shifting mysql to a dual core or dual proc machine help (vs a single core/single proc machine)? since there is just one mysql daemon, does having a second core or proc. buy me anything?
Hows everybody doing. I am hosting a small network of sites (between 5-10) on a dedicated server with HostGator. I have the Standard package which gives me 1024mb as far as RAM and a Dual-Core 3040 Xeon (Conroe) as a processor goes.
My sites run extremely slow on the front end and back end. The sites are blogs which you probably know are php heavy. Not to mention a few of the sites get a decent amount of traffic (Alexa rankings of around 50K). One of the less popular sites with not as much traffic is www(dot)abnormalstyle(dot)com ...You can see how slow this site loads, its on the same server as the other sites, just using a different IP account...
I am looking to upgrade my server. When i talked to HostGator support i got the answer i would expect. "Upgrade to the next package, which is more money".
I am wondering if i would advantage from just upgrading my ram, or going with a processor first. The thing is, if i want to get the next processor i have to defiantly go with the next HostGator package, due to the fact they cant just add a new processor. They can however add more Ram.
Below are some options, if you have the time feel free to leave your comments and pick one of the options below which you feel would best suit the network of Wordpress blog sites i am using.
Option 1 - Just upgrade RAM. There is no sense in going from a Dual-Core 3040 Xeon (Conroe) processor to just a Quad-Core 3210 Xeon (Kentsfield) processor, regardless of the ram, it will not make a major difference. ITS ALL ABOUT RAM!
Option 2 - Go for the next HostGator package which offers 4096mb Ram wise and Quad-Core 3210 Xeon (Kentsfield) processor wise. The Processor upgrade along with the RAM upgrade will be MUCH BETTER then just the ram upgrade itself in option 1.
After reading a lot of good reviews on Softlayer around here, I was thinking about switching to them. They have some really good deals and I'm planning on getting one of their dual opterons, but I have a question about the processor speed in relation to database intense stuff (like a forum with a good number of users on at once, or a CMS).
I have the option of either going for a Dual Opteron 248 (2.2 gHz) or a 252 (2.6 gHz) which costs $50 more. My question: is the 252 really worth the extra money compared to the 248? All I have on my server is an IPB forum with 100-450+ users on at any given time, and a static site (soon to be converted to a CMS), and I'm thinking that RAM is more important than the processor for a database app like those (that, and hard drive speed). So I wanted to know if it would be better to go with the 248 and spend the money on more Ram and a SA SCSI 10k drive or two?
I have a production windows 2003 server with 2 XEON processors. In task manager I see 4 processors: 0,1,2,3. I assume this is because these processors have hyperthreading. My question is how do I know which 2 of the 4 are the main processors. I have a service I only want to run on processor 2, which 2 would I select to do this? I really don't want to be experimenting as this is a live production server.
Planning on getting a new dedicated server with 4GB RAM, and a 500GB 7.2k SATA2 Hard Drive.
Which processor do you guys suggest? I know the Q6600 is older and runs hotter, but it has better specs than the Q8200. Would I really notice a difference if I'm only hosting static sites without any video streaming or anything?
