hey all. Although my app is far from complete, I thought Id do a little early 'load testing' to see what it would look like.
I had noticed awful big cpu usage times, usually anywhere between 1100ms to 5000ms on my / page ! ... After some memcaching (I had absolutely none before that), I was able to get it to reduce to the mid hundreds after a few loads. Anyway, here's what i did: My script sent gradual requests to my app, as I understand this is how to best test the load under gae. I dunno if these values are optimal, they were completely random: 10 requests 2 seconds appart, 20 more starting at 2 seconds and ending at 0.25 seconds apart, and then 15 more 'all at once'.I fetched / and then parsed the response for all a & img tags, and followed href's and src images. Then fetched those. I went 2 'levels' deep like that. I did not follow any forms. My first few 'simulated site hits' ran as slow as what I had experienced at first. But quickly enough, I saw cpu processing times drop dramatically. Now, this brought a few questions: first of all, I got an 'too much contention on entity' (or something like that) error, on my first attemps at a load test, which threw 100 requests for everything on my site all at once. I dont know what that error is, nor how do avoid it. second, I noticed that request times read like this /'url' 200'response code' and then a time mesure and then the cpu ms time. What is that first time mesure ? Is it the total amount of time spent ? Does it take into account any kind of latency on the client's side of things or what not or does this value indicate server ressources usage only? anyway, id like your input on that. in the mean time ill keep optimizing. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
