For best performance, use the TCP protocol when possible. The Connectivity Mode is configured during the construction of the DocumentClient instance with the ConnectionPolicy parameter.
Call OpenAsync to avoid startup latency on first request By default, the first request has a higher latency because it has to fetch the address routing table. To avoid this startup latency on the first request, you should call OpenAsync once during initialization as follows.
This latency can likely vary from request to request depending on the route taken by the request as it passes from the client to the Azure datacenter boundary. The lowest possible latency is achieved by ensuring the calling application is located within the same Azure region as the provisioned Azure Cosmos DB endpoint.
For a list of available regions, see Azure Regions. For example, if you're using. Use a singleton Azure Cosmos DB client for the lifetime of your application Each DocumentClient instance is thread-safe and performs efficient connection management and address caching when operating in Direct Mode.
To allow efficient connection management and better performance by DocumentClient, it is recommended to use a single instance of DocumentClient per AppDomain for the lifetime of the application.
You may need to set the MaxConnections to a higher value so that the client library can utilize multiple simultaneous connections to Azure Cosmos DB. DefaultConnectionLimit is 50 and to change the value, you can set the Documents. MaxConnectionLimit to a higher value.
Tuning parallel queries for partitioned collections SQL. Parallel queries are designed to improve query latency and throughput over their serial counterpart.
Parallel queries provide two parameters that users can tune to custom-fit their requirements, a MaxDegreeOfParallelism: Parallel query works by querying multiple partitions in parallel.
However, data from an individual partitioned collect is fetched serially with respect to the query. So, setting the MaxDegreeOfParallelism to the number of partitions has the maximum chance of achieving the most performant query, provided all other system conditions remain the same.
If you don't know the number of partitions, you can set the MaxDegreeOfParallelism to a high number, and the system chooses the minimum number of partitions, user provided input as the MaxDegreeOfParallelism. It is important to note that parallel queries produce the best benefits if the data is evenly distributed across all partitions with respect to the query.
If the partitioned collection is partitioned such a way that all or a majority of the data returned by a query is concentrated in a few partitions one partition in worst casethen the performance of the query would be bottlenecked by those partitions.
Parallel query is designed to pre-fetch results while the current batch of results is being processed by the client. The pre-fetching helps in overall latency improvement of a query. MaxBufferedItemCount is the parameter to limit the number of pre-fetched results.
Setting MaxBufferedItemCount to the expected number of results returned or a higher number allows the query to receive maximum benefit from pre-fetching.
Pre-fetching works the same way irrespective of the MaxDegreeOfParallelism, and there is a single buffer for the data from all partitions.
Turn on server-side GC Reducing the frequency of garbage collection may help in some cases. NET, set gcServer to true.
Implement backoff at RetryAfter intervals During performance testing, you should increase load until a small rate of requests get throttled.
If throttled, the client application should backoff on throttle for the server-specified retry interval. Respecting the backoff ensures that you spend minimal amount of time waiting between retries. Retry policy support is included in Version 1.
NET and Javaversion 1.The first approach will attempt to navigate the game object stack to find an instance of the GameManager which even though this only happens (or should only happen) once seems like it could be very unoptimised as scenes grow in size during development.

Serialization in Unity. Lucas Meijer, June 24, It makes me understand a little bit more on the core code of Unity3D. Thanks for sharing:) I had a game that I made (back in Unity version 3) that had a particular ‘levelblock’ prefab.
