[英]Slow Http Request handling in arangodb
My foxx application gets data in parrallel (about 5-6 http connection). 我的foxx应用程序以并行方式获取数据(大约5-6 http连接)。 I also have a simple url which just have
console.log('I am called')
. 我也有一个简单的网址,其中只有
console.log('I am called')
。 I have 4 core and 16gb of memory. 我有4核和16GB内存。 I am noticing that sometimes the following logs takes from 1 second to more than an hour to print
我注意到有时以下日志需要1秒到一个多小时才能打印
2016-03-12T17:02:53Z [11944] INFO /evm, incoming request from 127.0.0.1: GET http://127.0.0.1:8529/_db/_system/app/analysis/getStats
2016-03-12T17:02:53Z [11944] INFO I am called
I can see the cpu utilization is about 20% and memory utilization is about 50% only. 我可以看到cpu利用率约为20%,内存利用率仅为50%。
Can you suggest what could be the reason and where should I work on. 您能否提出可能的原因以及我应该在哪里进行工作。
I tried to reproduce it with ArangoDB 2.8.5 like this using a sample foxx service: 我尝试使用样本foxx服务在ArangoDB 2.8.5中重现它:
controller.get('/', function (req, res) {
/*
res.json(_.map(testRepo.all(), function (model) {
return model.forClient();
}));
*/
console.log('I am called');
});
and tried to tease it with this tiny shell snippet: 并尝试用这个小小的贝壳片段来逗弄它:
for j in 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 ; do \
for i in `seq 1 100` ; do \
curl -X GET --header "Accept: application/json" \
"http://127.0.0.1:8529/_db/_system/test/test" &\
done; \
sleep 2; \
done
but I see all loglines instantly appear in the arangodb logfile. 但是我看到所有日志行都立即出现在arangodb日志文件中。 Can you edit your question how to reproduce this?
您可以编辑您的问题如何重现吗?
