PostgreSQL Connection Pooling: Part 4 – PgBouncer vs. Pgpool-II

In our previous posts in this series, we spoke at length about using PgBouncer  and Pgpool-II , the connection pool architecture and pros and cons of leveraging one for your PostgreSQL deployment. In our final post, we will put them head-to-head in a detailed feature comparison and compare the results of PgBouncer vs. Pgpool-II performance for your PostgreSQL hosting !

The bottom line – Pgpool-II is a great tool if you need load-balancing and high availability. Connection pooling is almost a bonus you get alongside. PgBouncer does only one thing, but does it really well. If the objective is to limit the number of connections and reduce resource consumption, PgBouncer wins hands down.

It is also perfectly fine to use both PgBouncer and Pgpool-II in a chain – you can have a PgBouncer to provide connection pooling, which talks to a Pgpool-II instance that provides high availability and load balancing. This gives you the best of both worlds!

PostgreSQL Connection Pooling: Part 4 – PgBouncer vs. Pgpool-II

Performance Testing

While PgBouncer may seem to be the better option in theory, theory can often be misleading. So, we pitted the two connection poolers head-to-head, using the standard pgbench tool, to see which one provides better transactions per second throughput through a benchmark test. For good measure, we ran the same tests without a connection pooler too.

Testing Conditions

All of the PostgreSQL benchmark tests were run under the following conditions:

1. Initialized pgbench using a scale factor of 100.
2. Disabled auto-vacuuming on the PostgreSQL instance to prevent interference.
3. No other workload was working at the time.
4. Used the default pgbench script to run the tests.
5. Used default settings for both PgBouncer and Pgpool-II, except max_children*. All PostgreSQL limits were also set to their defaults.
6. All tests ran as a single thread, on a single-CPU, 2-core machine, for a duration of 5 minutes.
7. Forced pgbench to create a new connection for each transaction using the -C option. This emulates modern web application workloads and is the whole reason to use a pooler!

We ran each iteration for 5 minutes to ensure any noise averaged out. Here is how the middleware was installed:

• For PgBouncer, we installed it on the same box as the PostgreSQL server(s). This is the configuration we use in our managed PostgreSQL clusters. Since PgBouncer is a very light-weight process, installing it on the box has no impact on overall performance.
• For Pgpool-II, we tested both when the Pgpool-II instance was installed on the same machine as PostgreSQL (on box column), and when it was installed on a different machine (off box column). As expected, the performance is much better when Pgpool-II is off the box as it doesn’t have to compete with the PostgreSQL server for resources.

How to Connect HP Deskjet 2622 to WiFi By Expert

Connecting Hp Printers To Wi-Fi

You can easily connect HP Deskjet 2622 to WiFi by installing drivers and software.

• First, log into your system with administrator credentials. Stop all programs running in the background before starting to install the driver.
• 2- Disable the antivirus software before completing the software configuration. In progress, you can activate it after installation. Or just follow the instructions below:
• 3- You should have a HP printer operation guide CD.
• 4- Use the CD and complete the installation process.
• The setup process will begin and you will be asked to choose the nearest HP printer to connect to your network. It even gives you with another option to choose your preferred language.
• 6- A window will appear on your screen with various installation procedures.
• 7-We recommend Pro Suite because it provides a complete set of drivers and software. Includes wired and wireless options that suit you.
• 8- After selecting the settings, click the “Next” button.
• 9- Now select the wireless network where you want to connect the HP printer, and then click Next.

1. Before you set up your HP printer
   HP has developed a utility for the Wireless Setup Wizard that allows you to specify the security settings of the wireless network (such as SSID, network key, etc.).
   • Run this utility on the PC connected to the wireless network.
   • 2- If you need help in setting up and want to contact HP Customer Support, please make sure you have the SSID (network name) and network key.
   • If you don’t know this information (SSID and network key), you will not be able to proceed with wireless settings.
   • How can I find this information?
   • 1- Please refer to the documentation provided with your Wi-Fi access point/router
   • 2- The original SSID can be the manufacturer name or the model name.
   • 3- If you are not sure about the security information, please contact your router manufacturer, system administrator, or ISP.
2. Then, try to set up a HP printer on your Wi-Fi(wireless network)
   • To set it up, connect the power cord to your HP printer, and then plug it into a power outlet. Turn on your HP printer.
   • Then try to press the option “Menu” on the control panel.
   • Press the up or down arrow button to select a network, and then press OK.
   • Press the up or down arrow button to select Wi-Fi, and then press OK. (This step may not apply to all devices.
   • Press the up or down arrow key to select the setup wizard, and then click OK. SelectYes to enable the wireless connection.
   • This will display the setup wizard that is launched for the wireless connection.
   • The device will search your network and display a list of available network names (SSID). When the SSID list appears, press the up or down arrow button to select the SSID you wrote down earlier, and then press OK.
   • Do one of the following:
    1-If you use an authentication and encryption method that requires a network key (password). Enter the network key and click OK to apply the settings. Choose Yes to apply the settings.
    2- When your authentication method is an open system and the encryption mode is none. Go to the next step. 9-The device tries to connect to the selected wireless network.

Unpatched Wi-Fi Extender Opens Home Networks to Remote Control

The Homeplug device, from Tenda, suffers from web server bugs as well as a DoS flaw.

A popular Wi-Fi extender for the home has multiple unpatched vulnerabilities, including the use of a weak, default password, according to researchers. Also, two of the bugs could allow complete remote control of the device.

The flaws have been found in Tenda PA6 Wi-Fi Powerline extender, version 1.0.1.21, which extends the wireless network throughout the house using HomePlug AV2 technology.

“A compromised device can become part of an internet of things (IoT) botnet that launches distributed denial-of-service (DDoS) attacks, used to pivot to other connected devices, leveraged to mine for cryptocurrency or used in various other unauthorized ways,” explained researchers at IBM X-Force, in a posting last week.

Web Server Woes

The first two bugs are a command-injection issue (CVE-2019-16213); and a critical buffer overflow (CVE-2019-19505). They are found in the extender device’s web server, under a process named “httpd.”

The command-injection vulnerability carries a rating of 8.8 out of 10 on the CVSS severity scale. It arises from the fact that under the “Powerline” section in the user interface (UI) of the extender’s web server, the user can see and change the name of the other powerline communication (PLC) devices which are attached to the same powerline network. An authenticated user can inject an arbitrary command just by changing the device name of an attached PLC adapter with a specially crafted string, the researchers noted. Since the web server is running with root privileges, an attacker could leverage this injection to fully compromise the device.

“The name entered by the user is concatenated as an argument to the ‘homeplugctl’ application and being executed by the system’ library function,” according to IBM X-Force. “This user input is just URL decoded, without any validation or sanitation.”

The second vulnerability is found in the “Wireless” section in the web-UI: By adding a device to the Wireless Access Control list with a specially crafted hostname, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash. It’s listed as critical, with a 9.8 severity rating.

“It is possible to overwrite the return address register $ra and begin controlling program execution,” according to the analysis. “A motivated attacker can utilize this to potentially execute arbitrary code. Note that the overflow isn’t a result of an unsafe call to functions like strcpy or memcpy.”
