Recommended web server specs for box running multiple asp.net sites

  • 772

Can somebody point me in the direction of recommended hardware to satisfactorily run a web server that hosts several ASP.NET sites on IIS 6? Our stubborn sys admin thinks it's appropriate to only allocate 1 CPU and we are experiencing performance issues.

Thanks!

  1. I think your "stubborn" sysadmin is probably in the right here: 1 cpu of the size you mention in comments should be able to power a few high traffic or hundreds of low traffic sites. If you are pegging it out your code is broken and he's almost certainly trying to protect his hardware from your code. Anything that would take serious CPU time should be taken care of before traffic hits it.

    I suggest you do a review of your site architecture and code and figure out what's wrong with the big picture rather than throwing hardware at it.

  2. I tend to agree with Caleb.

    I run a ASP.NET server on Linux with mono and Nginx. It has 48 MB RAM and a 250 MHz ARM processor, and runs PostGre SQL as well. RAID-2, but no GUI whatsoever of course.

    It serves 150 to 200 people at times, and performance is good, site load never take longer than 2 seconds, even under full load. I'd say that's fantasitc for such low specs, especially considering that the database runs on the same system and that PostGreSQL is not the fastest database system I've ever seen.

    That's certainly not comparable with the requirements for windows, especially with IIS, which unlike Nginx, has a much high memory requirement, especially when it scales up, but I tend to fully agree with your sysadmin.

    Get a profiler, and see where the problem is.
