Performance update:
Authentication
Added Ed25519 signing support for NET8.0 and newer
Added static methods on ApiCredentials to create credentials of a specific type
Added static ApiCredentials.ReadFromFile method to read a key from file
Added required abstract SupportedCredentialTypes property on AuthenticationProvider base class
General Performance
Added checks before logging statements to prevent overhead of building the log string if logging is not needed
Added ExchangeHelpers.ProcessQueuedAsync method to process updates async
Replaced locking object types from object to Lock in NET9.0 and newer
Replaced some Task response types with ValueTask to prevent allocation overhead on hot paths
Updated Json ArrayConverter to reduce some allocation overhead
Updated Json BoolConverter to prevent boxing
Updated Json DateTimeConverter to prevent boxing
Updated Json EnumConverter caching to reduce lookup overhead
Updated ExtensionMethods.CreateParamString to reduce allocations
Updated ExtensionMethods.AppendPath to reduce overhead
REST
Refactored REST message processing to separate IRestMessageHandler instance
Split RestApiClient.PrepareAsync into CheckTimeSync and RateLimitAsync
Updated IRequest.Accept type from string to MediaTypeWithQualityHeaderValue to prevent creation on each request
Updated IRequest.GetHeaders response type from KeyValuePair<string, string[]>[] to HttpRequestHeaders to prevent additional mapping
Updated IResponse.ResponseHeaders type from KeyValuePair<string, string[]>[] to HttpResponseHeaders to prevent additional mapping
Updated WebCallResult RequestHeaders and ResponseHeaders types to HttpRequestHeaders and HttpResponseHeaders
Removed unnecessary empty dictionary initializations for each request
Removed CallResult creation in internal methods to prevent having to create multiple versions for different result types
Socket
Added HighPerformance websocket client implementation which significantly reduces memory overhead and improves speed but with certain limitations
Added MaxIndividualSubscriptionsPerConnection setting in SocketApiClient to limit the number of individual stream subscriptions on a connection
Added SocketIndividualSubscriptionCombineTarget option to set the target number of individual stream subscriptions per connection
Added new websocket message handling logic which is faster and reduces memory allocation
Added UseUpdatedDeserialization option to toggle between updated deserialization and old deserialization
Added Exchange property to DataEvent to prevent additional mapping overhead for Shared apis
Refactored message callback to be sync instead of async to prevent async overhead
Refactored CryptoExchangeWebSocketClient.IncomingKbps calculation to significantly reduce overhead
Moved websocket client creation from SocketApiClient to SocketConnection
Removed DataEvent.As and DataEvent.ToCallResult methods in favor of single ToType method
Removed DataEvent creation on lower levels to prevent having to create multiple versions for different result types
Removed Subscription<TSubResponse, TUnsubResponse> as its no longer used
Other
Added null check to ParameterCollection for required parameters
Added Net10.0 target framework
Updated dependency versions
Updated Shared asset aliases check to be culture invariant
Updated Error string representation
Updated some namespaces
Updated SymbolOrderBook processing of buffered updates to prevent additional allocation
Removed ExchangeEvent type which is no longer needed
