What should I do if I get this error: Fatal error: Maximum function nesting level of '100' reached, aborting!

You could run into this error if you have the XDebug extension installed and you execute a lot of requests in callbacks. This error message comes specifically from the XDebug extension. PHP itself does not have a function nesting limit. Change this setting in your php.ini to increase the limit:

xdebug.max_nesting_level = 1000

How can I speed up my client?

There are several things you can do to speed up your client:

1. Utilize a C based HTTP message parser (e.g. Guzzle\Parser\Message\PeclHttpMessageParser)
2. Disable operation validation by setting the command.disable_validation option to true on a command

Why am I getting a 417 error response?

This can occur for a number of reasons, but if you are sending PUT, POST, or PATCH requests with an Expect: 100-Continue header, a server that does not support this header will return a 417 response. You can work around this by calling $request->removeHeader('Expect'); after setting the entity body of a request.
