TSNE performance regression in 1.5

### Describe the bug

The performance of TSNE transformation reduces when using n_jobs as 25 for the newer version w.r.t. 1.3.1. 
version 1.3.1
```
df = np.random.rand(30000, 3)
tsne = TSNE(n_components=2, random_state=42, n_jobs=25, verbose=10, n_iter=1500)
```
1.5.1
```
df = np.random.rand(30000,3)
tsne = TSNE(n_components=2, random_state=42, n_jobs=25, verbose=10,max_iter=1500)
```
Time 1.3.1 vs 1.5.1 :: 59 vs 223

Is this a intended behavior?

### Steps/Code to Reproduce

```
df = np.random.rand(30000, 3)
tsne = TSNE(n_components=2, random_state=42, n_jobs=25, verbose=10, n_iter=1500)
```
1.5.1
```
df = np.random.rand(30000,3)
tsne = TSNE(n_components=2, random_state=42, n_jobs=25, verbose=10,max_iter=1500)
```

### Expected Results

Minimal time discrepancy 

### Actual Results

Similar time

COMMENT:
I have opened #29694 which I think fixes this issue.
