Subject [jira] [Commented] (IGNITE-12374) Too low performance ~200TPS for single ODBC client

Igor Sapego commented on IGNITE-12374:
--------------------------------------

[~yow] I checked out the sample code and I have a feeling that performance drop may be related
to atol and atof calls in sql_set_parameter. Need to check this though

> Hi, in our test ignite performance with ODBC connection is too bad to proceed with product
integration. It is about ~200 TPS, each transaction with select+update operation.
> Please refer to attach sample program. It is just a simple test case. 
> Based on the profiling most of the time consumed by sql execution. Please advice if the
application did not do the right thing.
> Thank you.
