Variable Explorer can take a while to refresh

[rchiodo]

Here's the code I was using:

#%%
import numpy as np
import pandas as pd
col = pd.Series(data=np.random.random_sample((700,))*100)
dfInit = {}
idx = pd.date_range('2007-01-01', periods=700, freq='M')
for i in range(3000):
     dfInit[i] = col
dfInit['idx'] = idx
df = pd.DataFrame(dfInit).set_index('idx')

#%%
# Index not working
df2 = df.iloc[:, [0,1]]

#%%
# Dataviewer not opening
row = df.loc[df.index[0], :]

Refreshing is stalling like so:
