12/29/2023 0 Comments Chromium uses in ww2![]() Chromium was utilized with superb effect in jewellery, both by French avant-garde designers and in cheaper mass-produced work where it was often combined with plastics. Lighting fixtures, clocks and such decorative articles as figurines and car mascots were also chromium-plated. The decorative potential of its colour and brilliance was quickly and enthusiastically recognized by the innovative designers of the 1920s and 1930s. As chromium is resistant to corrosion, it was used in World War I for projectile covers, although it was not until 1924 that it was commercially produced in the USA and Germany and later in Britain. Rarely used in its pure form, it is usually plated on to base metal above a coat of nickel, by a process that was first mentioned in 1854. It is widely dispersed in natural deposits as dark brown to jet black chromite, the largest producer being Albania. 1797 in France and was named chrome (Gr.: ‘colour’) due to the pigments observed in its compounds. if I had to guess, I'd say probably the latter.Lustrous silvery metal obtained from lead chromates by smelting or aquaceous electrolysis. So, basically, either something OTHER than Chromium is eating most of your RAM, or you have extensions installed in Chromium that aren't very memory-efficient and are significantly bloating it per process. I haven't tried to check to see how much omgubuntu eats specifically.Ī bit MORE reference: I set up a clean VM and installed chromium-browser opening 12 tabs to resulted in 1.3G used / 718M free (646M used / 1.3G free -/+ buffers/cache). So, yeah, they definitely do add up.įor further reference: those are my TOP memory-hungry Chrome processes I actually have 72 current tabs open right now and they're eating about 0.9% of my RAM (about 90MB-ish) apiece on average - the actual range is from about 10MB on the low end to about 600MB on the high end. Try to make it happen, then post output of free -m.Īlso, please post details on what make and model of hard drive you're using, and output of df -h.įor reference, here is me looking at the %memory used by the biggest processes currently running on my system: ps wwaux | awk ' ' | sort -rn | head -n 10Ĭan you run the same command on your system, please, and let's see what your biggest processes are?įor reference, my system has 16G of RAM, and each of those chrome processes you see is therefore eating something along the lines of 300MB-600MB of RAM. Memory usage of several Chromium extensions Perhaps a practical short-term solution.Ĭoming week I will report back about how much the performance of Chromium has improved when running without extensions. ![]() Disabling extensions like Offline GMail and Google Drive should make my system more responsive.Īnyone who has similar problems: Last week I have used Firefox instead of Chromium. ![]() Together, they used about 200-300 MB memory (see the list below). Several extensions however, were also running. No other processes except Chromium (chromium-browser) were running. Processor(s): Intel 1.66 GHz (Dual Core).I have no idea where to start looking for a solution. Output of df -h: Note: Filesystem(FS) Size(S) Used(U) Available(A) Use %(U%) Mounted on(MNT) The output of free -m when opening 12 OMG! Ubuntu tabs simultaneously: Note: Total(T) Used(U) Free(F) Shared(S) Buffers(B) Cached(C) Opening several new tabs at OMG! Ubuntu has the best chance to replecate this isue. It seems that the chance for increasing memory usage is when more complex sites like GMail and plugins like Flash are running. Several tabs have to be open, usualy 8 or more. The exact circumstances are difficult to replicate. Waiting until it's over takes more than 30 minutes, if it ends at all. This is way faster than starting a new terminal in X, just starting a terminal seems too heavy for Compiz under these circumstances. When my disk starts to spin like crazy and the disk activity LED is on continiously the system is so slow that it takes about two to five minuits to switch to tty6, log in and execute killall chromiumbrowser & killall chromium. However this problem always starts and ends with Chromium. (reading 2-3MB/s) Other processes (updatedb.mlocate,, Clementine, Compiz) show the same behavior. For some reason it sometimes uses 99,99% of I/O. My favorite browser Chromium is testing my patience.
