investigate performance for pipe()

[danisharora099]

Problem

With the investigation #1465 (comment), we saw that the delays in lightpush.send() are considerably tied with how long the execution of pipe() takes

Proposed Solutions

Investigate if we can cut down the time taken for its execution

Notes

• ref Delay during message sending #1465

No recent complains about performance of LightPush, closing as not needed
