StockChart performance

[Kristof]

Hi!

Since upgrading to v19 stock chart performance seems much worse. It takes about 3 times longer (3sec. vs 10sec.) for the stock chart to appear. Some parts of the chart (range selector and "header") appear even later.

Usage details: 

• Client side Blazor
• Candle chart with decimal values from an IEnumerable
• A second chart series for trading volume with long type
• Large number of data points (about 1000)
• macOS with Chrome

In the previous version (v18) rendering (of the same chart) was much faster. Please review your recent performance related changes. If you cannot reproduce the issue I happily share a comparison video.

Thanks for the support.
