HistoricalReferenceExtractionRequest very slow (C# API)
Hello, I'm requesting static data on several options chain RIC on a range of 10 days. It takes at least 1 hour to have a result. I will need the static data on the whole history (many years), what is the most efficient way to request the data ? Example of the code on 10 days: var extractionRequestStatic = new…

...empty dataframes The purpose of this case is to determine the ideal number of fields and assets to download in each query, to avoid null data or empty dataframes. I have noticed that when I try to download various metrics and assets, sometimes the data returned is null or the dataframes are empty. However, this issue is…

Getting Mutual fund time series data
Hello, for my thesis I have to obtain times series return data for several mutual funds (at least monthly, but daily would be better) from 2000-today. However, the data is not available in Eikon (for example when I try it with the build formula tool in excel). Is it even possible to get return data for mutual funds in…

Seeking Performance Improvement Advice for High-Frequency Batch Requests
I'm currently conducting performance testing on batch requests with Refinitiv ADS server and encountering some issues with response times in high-frequency scenarios. I would appreciate any advice to improve performance. Scenario 1: * Frequency: 1 batch request every 20ms * Each request: contains 10 RIC codes * Totoal…

[EMA/C++] FieldList/UpdateMsg performance with multithreading
Hi We're in the process of developing a C++ application that will utilize RTSDK to send a rather large amounts of messages (200k+) in periodic bursts. We're basing this on Cpp EMA, and we're running multiple threads each with its own InteractiveProvider to spread business logic and encoding load between different CPU…

Api performance seems to have decreased
Hi, We have been using permID for a while now and just this last weekend have found that the response time has massively increased. Testing today with calling the match api (https://api-eit.refinitiv.com/permid/match) with the following body: name google it took 55 seconds before we got a response, we used to be able to…

EMA performance not comparable to IDS rest interface.
We are moving to the cloud and it has been suggested to use Java EMA to connect to our ADS service. It works fine for a few rics but when sending 1000+ rics the performance is much slower than when we were doing the same thing against the IDS restful interface. We basically just want to replicate the functionality of the…

Eikon python API not responding?
I have a function that runs and pulls in Benchmark Yields (I.e. US1YT=RR, EU10YT=RR, etc) for a list of 100 currencies. Currently, the function is freezing randomly in the data pull request stage from ek.get_data() where no error message or data is returned. The code is just running with no response. This occurs randomly…

rsslRead and rsslDecode functions latency spikes
Hi We have measured the latency of our UPA consumer application, and have noticed some unusual behaviour around the rsslRead and rsslDecode functions. Attached is a graph displaying our findings. Our measurements are showing that the first call of rsslRead takes longer than subsequent calls for message 'bursts' from the…

RFA JAVA API Performace (wrt numbers of GC and compared to RFA C++)
We are in favor of choosing the RFA JAVA API. Is the API efficiently built in terms of garbage it generates? Since our application is latency sensitive, we expect no major GC cycles due to garbage from RFA JAVA API. Also, Is there a recommended API to choose between RFA JAVA and RFA C++ APIs due to performance benefits.?…

DSS .NET SDK performance issues - ondemand extract
We are trying to fetch EOD prices through on-demand extraction .NET SDK for more than 10k instruments.This takes 20+ minutes to complete which is almost 10 times longer than time taken while using http endpoint. Is it to be expected or we can do something to speed it up. If you need more information, please let us know.…
