How to use Java on Google App Engine without exceeding minute quotas?
- by Geo
A very simple java code inside a doGet() servlet is getting more than a second of cpu time on GAE. I have read some quota related documentation and apparently I am not doing anything wrong.
//Request the user Agent info
String userAgent = req.getHeader("User-Agent");
I wanted to know what was using the CPU the most, I use a google help recommendation.
//The two lines below will get the CPU before requesting User-Agent Information
QuotaService qs = QuotaServiceFactory.getQuotaService();
long start = qs.getCpuTimeInMegaCycles();
//Request the user Agent info
String userAgent = req.getHeader("User-Agent");
//The three lines below will get the CPU after requesting User-Agent Information
// and informed it to the application log.
long end = qs.getCpuTimeInMegaCycles();
double cpuSeconds = qs.convertMegacyclesToCpuSeconds(end - start);
log.warning("CPU Seconds on geting User Agent: " + cpuSeconds);
The only thing that the code above tells me is that inspecting the header will use more than a second (1000ms) of cpu time, which for Google is a warning on the log panel. That seems to be a very simple request and still is using more than a second of cpu.
What I am missing?
