          Hi,

           

          The performance issue you are experiencing is most likely due to a security fix implemented in Flash Player 30.  See Spectre/Meltdown Mitigation section of the Flash Player 30 Release Notes, including information on a work-around.

              Spectre / Meltdown Mitigations

               

              In response to a class of recently disclosed vulnerabilities in popular CPU hardware related to data cache timing (CVE-2017-5753, CVE-2017-5715, CVE-2017-5754), known popularly as Spectre and Meltdown, we are disabling the ‘shareable’ property of the ActionScript ByteArray class by default.  Administrators can turn this feature back on using the following MMS properties:

               

              EnableInsecureByteArrayShareable

              Short Description:
              Allows Administrators to override the Flash Player 30 and above default behavior of restricting the “shareable” property of the ActionScript ByteArray API class.

              Detailed Description:
              EnableInsecureByteArrayShareable = [0,1] (0=false, 1=true)

              This setting will allow Administrators to override the Flash Player 30 and above default behavior of restricting the “shareable” property of the ActionScript ByteArray API class. Shared ByteArrays are used to share data between threads with ActionScript “Workers.” Shared ByteArrays are an advanced feature of the ActionScript API set and not commonly used in the vast majority of published Flash content. For increased security, we recommend administrators leave this feature disabled.

               

              EnableInsecureByteArrayShareableDomain

              Short Description:
              Allows Administrators to override the Flash Player 30 and above default behavior of restricting the “shareable” property of the ActionScript ByteArray API class on a per-domain basis.

              Detailed Description:
              EnableInsecureByteArrayShareableDomain = domain name or IP address

              By default, Flash Player 30 and above will no longer allow the “shareable” property of the ActionScript ByteArray API class. The EnableInsecureByteArrayShareableDomain settings provide exceptions to that rule. Administrators can create a “white list” of approved domain names or IP addresses to which the EnableInsecureByteArrayShareable setting will apply. If the active security context is in the list of domains and IP addresses, then access to the sharable ByteArray property will be allowed. Otherwise, sharable ByteArray access will be denied.

              For domain names, prefixing a * wildcard is allowed. For example, *.adobe.com would allow all Flash content with the “shareable” property to run on www.adobe.com, get.adobe.com, helpx.adobe.com, and so on. Wildcards are not allowed when specifying IP addresses.

              For example, the following settings allow SWFs using the shareable ByteArray property to only run on servers at www.mydomain.com and 10.1.1.10:

              EnableInsecureByteArrayShareableDomain=www.mydomain.com
              EnableInsecureByteArrayShareableDomain=10.1.1.10

              For domain names, prefixing a * wildcard is allowed.

              Example:

              EnableInsecureByteArrayShareableDomain=*.mydomain.com

              This would allow all Flash content with the “shareable” property to run on www.mydomain.com, foo.mydomain.com, and so on. Wildcards are not allowed when specifying IP addresses.

               

              EventJitterMicroseconds

              Setting this value to 0 disables an important mitigation for Spectre and Meltdown (CVE-2017-5753, CVE-2017-5715, CVE-2017-5754) style attacks, but may improve application performance in some limited circumstances.

                  Well ... I found this file what I would do by asking for more clarification

                    Not sure what you mean.


                    While we provide the ability to disable the security mitigation, this is a work-around isn't really recommended as it disables the security measures implemented.  Ideally, the content provider fixes their content to work-around this change.

                        What you need to do before proceeding is understand the consequences of turning off security fixes. It's like choosing not to lock your car or house because you are fed up of carrying keys around. Do you know the risks and accept them? Do you ever use the same computer for personal information or shopping?
