Learn English – “we have different rhythms” vs “we have different paces”

There are two famous sayings that most native English speakers know:

Music soothes the savage beast.

and

Far from the maddening crowd.

The problem is that, while "everyone" knows them, they're both wrong. The actual quotes are

"Musick has charms to soothe a savage breast."
The Mourning Bride, William Congreve

and

Far from the Madding Crowd
Thomas Hardy, 1874

The reasons why people remember the wrong versions are varied and not important - but I bring them up because a café opened here named "Far From The Madding Crowd". A good name for a café as a place of respite from the daily grind (pun intended...).

But literally every day more than one person came in and told them that their sign was wrong. They ended up making a big sign inside explaining that the name was right, the customer had been told the wrong thing, and they weren't going to change the name of the café. And still people insisted that the sign was wrong - they refused to learn.

This is one example of why naming something that people think is incorrect is a bad idea. It may make it memorable, and you may teach people something (if they're willing to learn), but you may also alienate them instead.

Some names are deliberately misspelled, with a *wink* to the reader, and people think "Oh, that's clever!" Sorry, but in my opinion "lightninged" isn't one of those.

This is an extract from a quite technical document. In addition to the problem of understanding the English constructs, you have second challenge in that certain terms have specialised technical meanings. Here we see process being used in a very particular way, as well as processing being used in a subtly different but related way.

In understanding this passage you need to identify the technical terms and establish their meaning in this particular document. You cannot do this simply by reading this one paragraph. We would hope that there would be a glossary for this particular document that would define the terms, however there may well not be one, so instead we at least need to look at a technical dictionary (for example), we cannot simply appeal to standard English usage.

So here you need to know what process, web server, request, concurrent and processing mean.

From my own knowledge of this field the Web Server is a particular process running on a computer, there will be many such processes running. The Web Server has responsibility to receive requests (typically from a Browser) and performs processing to satisfy those requests.

Here we come to the meaning of on behalf which can mean in the interest or aid of. So for each request some processing is done, that processing is on behalf of a single request.

The key idea is that the Web Server is satisfying multiple requests at the same time concurrently. And the issue being addressed is what happens is one request's processing effectively monopolises the Web Server for a period of time, in this case the other requests, concurrently being processed are stalled until the monopolising processing is finished.

Hence to understand this paragraph we need to get definitions of some technical terms but also need some quite detailed technical background information about multi-threaded concurrent processing.

The only slightly tricky English here is the on behalf, which becomes clear when we understand the relationship between a request and its processing.
