Please find my answer in-line for your query:
1. How App42&AppWarp performance is effected by "instantaneous active users" (25.000 instant online users for example)?
Ans: Our systems are deployed in scalable environment transparent to end users. In case of high traffic, System will scale itself to meet the high traffic requirement. But having said that in case of our multitenant solution, SLA is best effort. For customers like you who want committed SLA, we do have option for dedicated deployment as well.
In case of storage, we implicitly take the measure to optimize the same. we also support customized indexing on your data.
2. From another perspective to question 1: How App42&AppWarp performance is effected by "instantaneous number of query to the server"? Is there a bechmark like this one: http://appwarps2.shephertz.com/dev-center/deployment/benchmarks/#private-message-test-light
Lets think about that, 25.000 online active users make a query to server to fetch something at the same time. Will server response to all of these individual queries in a meaningful time(1-2 seconds)?
Ans: As answered in the first query, the system will adjust itself to meet the high traffic requirement. Server response to all of the individual queries will remian same.
But at the same time, it is designed to serve the calls to our servers as per the package subscribed. For example, If you are subscribed for Large ($199/month) package which has a quota of 40 million API calls and once your API calls has crossed the specified limit to certian extent, you will just be charged for the extra API calls. In case of extra API calls are too high, we recommend the user to upgrade to higher plan.
NOTE: If you have a requirement of high number of API calls, you will have to get the Burst limit increased by sending your requirement to App42 Team.
3.How App42 "response time" performance is effected by "Fullness of a collection"? Forexample: We have a custom collection that stores users game data. There are 10 elements in this collection right now while we are testing and response time of server is ok(1-2 seconds). But what if there are 10M element in this collection? Response time will be still 1-2 seconds? These answers will be very important not only for us but also all of your potetntial users. Thanks.
Ans: Response time to fetch the data from a collection depends on the query being executed and data inside the collection. As answered in first query, System has been optimized in such a way that it would take the minimum time possible and it is also possible to run customized indexing on the huge data inside the collection.
Please let me know in case you have any concern. I will be happy to help!!!
