    Max amout of sites on a server

    What is the max amout of websites that "SHOULD" be hosted on a website?

    I did a whis.sc on my sever and I found that it currently has: 495 websites on it.

    Server specs:
    Dual Xeon 2.4 Ghz with Hyperthreading w/ 1GB RAM
    OS: Fedora

    Is this good, bad, does it explain recent mysql, and server downtime?

    What should I say to my host?

    Depends on the sites. What is the server load like?

    A server like that can hold 2000 sites or 1 site, just depends on how heavy the usage is. There is no magic number of sites per server.

    here is other information from cpanel:

    Server Load 0.69 (4 cpus) - If I could monitor this # I would provide you with an average load use. So this isn’t accurate.

    Nothing there that really helps too much, the load is the number that you have to be concerned with and .69 has not even gotten that server breathing hard yet.

    You really need to see a mrtg graph or be able to watch top for while to tell for sure.

    We run about 1500 plus sites on that same config Dual Xeon 2.4 Ghz with Hyperthreading w/ 1GB RAM or 2 GB Ram if needed. But we use FreeBSD as well. I don't think 495 websites and a .69 load is bad but that might not be there peak time ether.. We see our load go up to about .80 at our peak at times, but that is a very low load for 1500 sites and peak time..

    It really depends on the type of websites you are running. On the Dual Xeon boxes we run, we put approximately 1200 to 1500 sites as well and it handles very well. We normally have 4GB of DDRAM on the box with 2, 73GB SCSI hard disks in RAID1 or 3, 36GB hard disks in RAID5. The SCSI hard disks have an inbuilt controller (not a CPU controller like IDE hard disks) so CPU load is considerably less for us (it averages 20%).

    I think Techark summed it up right there. There is no magic number because a server could hold thousands of one-page sites, or a high-traffic site could require an entire server. We limit our dual Xeon and single-cpu servers to about 500 domains and it seems to work well. With that number we've never had a hard drive get full, and the servers perform well except in the rare case of abuse.

    500 websites, 0.6 load on a server of that spec means the server is flying is along.

    The amount of sites and server specs has nothing to do with MySQL or HTTP downtime. Just one site on a server can be responsible for taking both down.

    Always hit less than the theoretical number so you have room for other sites to grow.
