Performance issues #1357

KostyaLocal commented 3 months ago

Hello, I am using Bybit and Binance packages. Binance consumes almost 10 times more CPU time, profiler shows the time in waiting for data in sockets. Can you check ?

Hi, both libraries use the same websocket mechanic under the hood, assuming you're using the latest versions. Could it be that Binance just processes more data? If you can provide some more context I can have a look:

Library version numbers? Which subscriptions are you using on both libraries? Is this happening immediately or after some time?

Could it be that Binance just processes more data?

No. I am using Binance UsdFuturesApi's SubscribeToUserDataUpdatesAsync + SubscribeToKlineUpdatesAsync, the last one has update frequency 250ms

Bybit: SubscribeToOrderUpdatesAsync, SubscribeToPositionUpdatesAsync, SubscribeToWalletUpdatesAsync (V5PrivateApi), SubscribeToCandleUpdatesAsync (V5LinearApi) Bybit has 100ms frequency updates on candles

Versions are latest from nuget: binance 9.6.1, bybit 3.6.1

I can't figure out what the function is. The load is immediately high after subscribing to updates. On a normal pc/laptop cpu usage is not felt, but when the application runs in the cloud on 1 shared CPU, the difference is noticeable Screenshot_9
