How to improve network clients performance
IMPROVING CLIENTS PERFORMANCE
After installing Bitdefender Client on the network stations you may notice a minor computer slowdown, specific to all real-time scanning security solutions. However this mentioned slowdown should not render the computer unusable (complete freeze), nor should it dramatically impact the overall computer performance.
In such cases or if the computer is slowed down more than expected or just to reduce the slowing degree, you may consider the following:
Check for any other security solutions on the respective clients (anti-virus, anti-adware, anti-spyware, firewalls and so on) and make sure to remove them. Our recommendation is to keep Bitdefender Client as the only security solution installed and active at one point in time. Note that even the on-demand scanning tools may install some monitoring drivers or may implement some indexing mechanisms (for performance regards) that could lead to a computer slowdown after Bitdefender client is installed;
- Check for logon scripts, batch jobs or indexing services. All these processes require intense hard-disk activity in terms of accessing old files or creating new ones - all files accessed or created are scanned by the real-time protection module of Bitdefender. Try to filter these processes and keep only the needed ones while disabling or uninstalling what is not necessary. Additionally make sure to create some exclusions from scanning (install paths for these applications, working directories or used extensions exclusions). Alternatively the real-time protection can be temporary disabled but this action is not recommended.
IMPROVING NETWORK TRAFFIC SPEED
In the previous chapter we discussed about how to tweak each individual network client. This section covers the interaction between two or more protected network stations or servers.
Saving files on mapped network drives. In some environments remote files are opened directly from the shared folders and saved directly on the initial location after being worked on. The default configuration of Bitdefender Client will scan this file twice when saving: first, Bitdefender will scan the local temporary file created at the opening of the file and again remotely, after the file is closed on the remote location (mapped network share). If you add a security solution on the remote station or server then the file will be scanned three times in the same time frame - thus a possible time-out (error message) when saving. In order to avoid this situation you need to exclude the respective remote network shares from scanning on the client side using the Exclude path option. When talking about excluding these network shares there are two entries needed for each share: the mapped network drive (e.g. M:\) as well as the UNC path (e.g. \\remote_computer\share_name). Additionally, extensions exclusions may be needed here as well;
- Client-server applications. Usually there is at least one client-server type application within each network environment. If the client-server application uses mapped network shares to work then the recommendations are the same with the ones described at Saving files on mapped network drives. If the client-server application uses another communication protocol (and does not include working on network shares) then the only recommendation is to exclude the extensions from scanning.
Please note that all exclusions presented above can be made either directly on the clients or via the Configure client task in Bitdefender Enterprise Manager. In certain cases, the default number of scan path exclusions provided by Bitdefender Enterprise Manager may prove to be too little. In order to expand this number please read our related article.
