I was hoping to get some guidance in setting up my WeBWorK server. My issue is that some students are complaining about slow page loads and "page not found" errors when they submit answers to their questions.
Not all students are having this complaint, interestingly. In particular, one of my classes has gotten only true/false and multiple-choice questions, and they have not gotten any page-not-found errors.
I have tried things like filtering the classlist by section number and then I too get the page-not-found error. However, I was able to filter by section number one time (out of around 10 attempts), but it did take a while. I'm somewhat perplexed by this issue and hope someone here can chime in with server settings suggestions.
I recently migrated to a decent server, so I don't think lack of resources are the problem. Here are the stats:
![server_stats server_stats](http://reedleywebwork.online/server_stats.png)
I've seen the RAM usage go as high as about 2GB.
Also, I don't think I've been hacked. Here is the output of top:
![top_output top_output](http://reedleywebwork.online/top.png)
The above loads are fairly typical, I'd say. Sometimes there are more processes (close to deadlines), but I've never noticed anything using more than 5% RAM.
My question: given the stats of my server, what settings should I try to make the user experience best for my students? I installed using default settings on aubreyja's recent script except for upping a certain parameter to 80 (I forget the parameter, but it said something about 20 _____ per each GB of RAM is a good guideline). I think it was worker or child, I don't remember.
Your ideas are welcome. Thank you for everything you do for this project!
