The issue is always with Wine. Wine has very very very inefficient handling of socket receive buffers and probably send buffers as well. The simple fact is even with a single buffer, Wines network I/O performance is below 50%, or even lower, of what Windows provides, at least with the network I/O model that Sierra Chart is using which utilizes overlapped I/O and I/O completion notifications. Wines performance is absolutely terrible in this area. If you perform a data download following this method and then post the log messages related to that we can see if a single buffer is being used and can confirm if the buffers are functioning as they should be: Follow the instructions here to clear the Message Log: Message Log: Clearing the Message Log Fully re-download the data in the chart by going to the chart and selecting "Edit >>Delete All Data and Download". Or, in the case of a Continuous Futures Contract chart, follow these instructions: Continuous Futures Contract Charts: Re-Downloading Continuous Futures Contract Data After about a minute provide a copy of the Message Log following these instructions: Support Board Posting Information: How to Post Your Message Log (Required In Some Cases) We will then determine what the problem is.
