MySQL processes frequently account for of CPU usage on the server. After using the show processlist command, you can see many SQL statements in the locked status. Use show status like 'table % 'to check table_locks_immediate and table_locks_waited. It is found that table_locks_waited is too large. The problematic table is MyISAM, which is probably caused by the MyISAM Table lock. MyISAM is suitable for reading frequencies much higher than writing

ratio, and the size is almost the same as that of P,In this case0 1 2 3 4 5I pInstead, we can get a better compression rate.(Because 1 p references 0i, the gap is small. 2 P can refer to 1 p, and the gap is small. And so on ....)Now, the dynamic allocation of XviD is much better than before, and the maximum number of B-frames can be safely set to 4.For B-frame of DivX 5, the maximum number of consecutive frames can only be 1. It can only be I B p B,Not to mention the advanced I/P/B frame alloca

. The sampling rate is in the unit of H z. Sampling 1 0 0 0 times per second is 1 0 0 0 0 h Z or 1 k h z. The sound must be 88 200 bytes per second. Stereo requires twice the storage space, because two records need to be recorded to achieve the effect of stereo. However, when the sampling rate is 4. 1 k h z, only 8 seconds of music can be stored on a 1. 4 4 m B floppy disk. A typical rock roll (4 5 minutes) requires 4 7 5 m B.Example of waveform file Calculation Sound Card processing quality can

802.11ac and 11n standard? To put it simply, the 802.11ad standard, also known as Wiig, can be considered as the next generation standard after 11ac and 11n. Compared with 802.11n (working in the GHz and 5 GHz frequencies) and 802.11ac (working in the 5 GHz frequencies), 802.11ad operates in the 60 GHz frequencies, making it easy to transmit data to 7 Gbps, it i

system that only uses OFDM, but for the IEEE802.11b system that is backward compatible and will replace at GHz, the data rate has been greatly improved. The compromise shows that IEEE802.11g has a great advantage. For the current IEEE802.11g system, every AP monitors the mobile devices next to it. If there is no IEEE802.11b device, the system will automatically cancel the RTS/CTS mechanism and increase the system throughput accordingly. In the future, when IEEE802.11g system completely replaces

(frequencies), and location files respectively.(Positions) Save. The dictionary file not only stores each keyword, but also retains the pointer to the frequency file and location file. The pointer can be used to find the frequency information and bit confidence of the keyword.. Lucene uses the field concept to express the location of the information (such as the title, article, or URL). In the index being created, the field information is also record

-cyclical signals, we need to use an infinite number of sine curves with different frequencies, which is impossible for computers. Therefore, only discrete Fourier transform (DFT) can be used for discrete signal transformation. for computers, only discrete and finite-length data can be processed, other transformation types are only used in mathematical calculations. In the face of computers, we can only use the DFT method. What we need to understand l

In traditional multi-carrier communication systems, the entire system band is divided into several sub-channels (carriers) that are separated from each other ). There is a certain protection interval between carriers, and the receiver uses a filter to separate each sub-channel and then receives the required information. This can avoid mutual interference between different channels, but at the expense of frequency utilization. In addition, when the number of subchannels is large, it is almost imp

positive gain is relatively compact. My personal experience is also related to the brightness of the sound in the audio center near 1.3khz. An appropriate improvement can increase the brightness of the sound, but it is usually not more than 3.5db (this value is purely personal experience, for reference only. 7. 2.5 kHz, 3.2 kHz, 4 kHz these three frequencies are related to the sharpness of voice, that is, the sound penetrating force. In compar

The issue of Playboy published by Rena is the best in its history, A total of more than 7 million copies were sold (the purchasing power of geek is amazing !). the copyright storm has passed, but the Reina diagram dispute continues. 3. The competition for technology is not perfect. Why is Reina tu so popular? David Munson, editor-in-chief of the I

It reflects the signals such as Bell streams and return-tone busy tones in the idle state. Inter-board signaling refers to the signal between the switch and the switch, which is used to control the connection and disconnection of calls. There are two types of functions: Line signaling and route signaling. Acco
