Is there any memory limit for Google Chrome browser?

Question

What is the default memory limit for a single tab in chrome ??

Answer 1

You can have a perfect answer once you benchmark on a specific platform with a specific version. The outcome will only be applicable to that platform and chrome version you experimented because there is so many factors that may have a different effect in results including,

1. The Chrome Version may have different v8 engines and not all v8 engines have the same memory limits. Also, the 32 bit and 64-bit architecture come into picture when we benchmark the chrome. The default heap size may varies from v8 version to version.

2. The system configuration on which you run the chrome. chrome requires the graphics memory/video memory and when you don't have that, It will use internal memory resulting in more memory usage.

3. It's also related to process itself, every thread requires some memory for bookkeeping, notably its stack. 32-bit processes can only address 4 GB of memory. 64-bit processes don't have problems with address space, but rather with the actual allocations. However, programs should not approach any such limit or need to worry about it and the same applies to chrome as well.

I tried once to export and print the database from PHPMyAdmin from chrome. It had 1.22GB of size in DB and chrome crashed. Same thing I performed to file export and magically it worked fine.

About the v8 engine, it has 512MB memory limit on 32bit system and 1434MB(1.4 GB) on 64bit system. The chrome has v8 it's heart, this is a major factor affecting the memory limit.
