Much slower loading speed of bigwig data in v3.3.0 compared to v3.2.6. #1995
Description
I pre-defined approximately 30 bigwig tracks to be loaded using JavaScript. When I used igv.js v3.2.6, all the bigwig tracks loaded very quickly, taking only a few seconds. However, when I switched to igv.js v3.3.0, the same process took several minutes to complete.
Although this issue was resolved when I used igv.js v3.2.6, the extremely slow loading speed in v3.3.0 (the latest version) remains puzzling.
