I am seeing a heavy lag in the display of plots in the developed shiny app that uses a large genomic data file as input. The example file is 60000 rows and 25 columns. Alternatively, the user can input a file of similar or larger dimension. The tool will be used to display visual plots, namely boxplots and scatter plots on the calculated on row-wise measures of the dataset (such as variance, interquartile range, etc). I understand that the dataset is quite large in dimension and size 1.6 MB.
A loading bar added that shows the progress. The processing takes about 30 seconds but the plots take over 60 seconds to be rendered on the chrome browser which is unreasonably high. When using Firefox, an unresponsive script issue is seen with a message saying it's causing the browser to slow down.
The tool is available using the web link below,
The log files are attached below:

Any help in this regard would be helpful to minimize the lag between analysis and display.
